I have an HD2 with SPL 2.08 and radio 2.15 , WinMo rom - Dexter .sencity 21.11 .
I have tried with other combinations too. My SD card is the original class 2 2gb micro SD. When I install Desire rom it works fast and everything is fine. When I put a Desire HD rom however it is slow - i takes 1-2 secs for it to open keyboard or the menus and so on. I dont know what the problem is or how can I see exactly how slow it is. Any help would be much appreciated! It is odd that people report that the Desire HD roms are really fast when they are slow on my HD2. Probably I messed up something but I dont know what so please HELP! I have tried different roms from m-deejay and Sergio76 and so on. The Froyo stock roms also work fast and flawless. I know there is another thread but it is in another section and there are no responses because this sections has 100x more activity. THank you!
Man honestly to rule out any possibilities of the ROM being the factor you have to use a class 6 or above sd card, otherwise you have no way of really troubleshooting what your problem is. Also, Devs mention in the releases all the time the Radio and WinMo ROM they use so to insure the same performance they can only give you what they are running as well.

The class of the SD card has nothing to do with it. The majority or people that have tried a class 4 and above say it is a lot worse than the stock SD card. I have tried and it was a lot worse for me also.
The Windows ROM and radio can have a LOT to do with it though.

By the way, how long exactly did you give it? These HD Roms can literally take hours to settle in and they won't be real speedy until they are completely done syncing everything. I have noticed that sometimes you won't see the sync icon but things will still be syncing in the background, inlcuding the Android market because these new Roms backup all your apps and data with the market and HTC sense. I am using Sergio76's and it is flying so I would try again but give it a lot of time to settle. Hope it works out for you, good luck!
As Motoman said, it will take time for everything to sync, but many reboots is very important. I have been using Mdeejay's Desire HD 4.1 for three days now, and don't have any problems. I must have rebooted 8-10 times the original day and that helped extremely well with speed.

At worst a class 6 card (for example) might not provide much in the way of an improvement over a stock class 2 but there is no way it would be 'a lot worse'.
Personally, I noticed a speed increase on identical builds when I swapped from my class 2 to a class 6 but nothing too drastic.

I agree with motoman that sdcards have nothing to do with the speed they might make a very little difference which can be negligible, I am suffering from a lot of lag in desire HD builds............
@motoman234, so can you tell us how exactly we should install these desire hd roms ?,
i was having the same issue with the hd roms. i thought they were terrible. i now have MDJ FroYo HD v.4.3=-[kernel:MDJ S7.5HD] running very well. i had to change my rom to achieve this. the wmrom is useless IMO but it lets me run android hd now. i am using this rom
ChuckyDroidROM-HTCFrameworkEdition.Nov.05.7z
and this radio
Radio_Leo_2.15.50.14
i also install bsb tweaks in winmo and set to power save mode. turn off everything in winmo and auto boot to android with hard keys lit up.
it works for me
Same issue as OP here. All non-HD ROMs run really fast. But other Desire HD ROMs are plain terrible speed-wise. I have a good Class 6 card.
It's a kernel issue. There is nothing you can do.

To each is own I suppose. I can only speak for myself when I say that a class 6 card made me have SOD every time when waking the phone from sleep, not to mention overall less performance. Not sure what it is about them but it was bad in my case but I doubt every single person will experience this.

It is a bit time consuming to get them rolling smooth for the first time but these are the steps I usually use when installing them for those of you that can not get them running like they should.
1) Boot up the build (fresh start)
2) Wait a couple minutes before unlocking the screen for the first time.
3) Setup everything in the SetupWizard.
4) From the moment you hit the "Finish" button on the SetupWizard, set your phone down for about 30-45 minutes before touching anything (OFF the charger if possible since it can get really hot when it is syncing everything for the first time. Charging can just add to that heat)
5) After you notice things to get a little faster, reboot the phone and then boot back into Android.
6) Wait another 5 minutes before unlocking the phone.
7) You should be good to go, if things still seem a little laggy try to reboot one more time.
I know this seems overboard but these HD builds have a lot to them. After you get the process over with you should be happy you did it. Once again **This is just what works for me** I am using Core Droid V0.2 by the way.
@Motoman234,
Not overboard...it's good advice. Thank you for the steps! P.S. Good to see a chef from my neck of the woods! Thank you sir!!

The Speed of the SD card has nothing to do with the roms performance.
The only difference that we will feel between a 'Class 2' and a 'Class 6' is when copying files to or from the SD card.
I noticed that on my 16GB Class 2, I have a transfer rate up to 4 MB/s when copying the Android folder and this card is supposed to have a maximum of 2mb writing while on my 8GB Class 6 I can copy up to 10 Mb/s the same Android folder (twice as fast).
But when Android runs I don't feel any difference at all.
The reason why the Desire HD roms are slow on the HD2 is because these roms were optimized to work under 768 MB RAM while our HD2 has only 576 MB RAM.
We barely have 100MB of free RAM with a Desire HD rom but with a stock rom we can have 300MB and more free.

I think what makes it worse is that we dont get 576mb ram in android, as this has not been built into kernels, we are only getting about 350mb of ram. If I check my available ram it is around the 300mb mark and has never been above 350mb.
u must just reboot you device after 1-st boot

Yes,the secret of having a good performance on any device is to have 1/3 of the amount of RAM always free.
For ex if you have 3GB of ram,you can use till 2GB and you will be very good.
But if you use 2.1 GB of the 3GB then don't think twice and upgrade immediately.
We are using this equation on our servers and t works pretty well,at least for our company.
I've only tested desire_hd beta and Core Droid HD v0.2 so far. Nonetheless, both have been quick and solid here. Like mentioned by motoman234, give these builds time to sync your market apps and settle down, then reboot a couple times, and you should be good to go. If the build has heavy lag, it's most likely still trying to download your market apps and install them as well as sync your personal data. Patience is key here.
Also, this goes for every build, but make sure that your keypad lights are on when booting into android. Doing this has normally solved any high standby battery drain that I've run into to date.
As far as MircoSDHC cards go, I have tested a handful of different class and size cards with the HD2, and found that once the system is booted up, there's no difference, or the higher class cards have more SOD or freeze issues for some reason. The HD2 can only handle so much, and random read speed appears to be the most important factor. In turn, a good quality class 2 card should be all you need. That said, I've been running a Sandisk 32GB class 2 card for months now, without a single problem to date. Regardless of what card you use, I highly recommend using SD Formatter in quick format mode.
Another thought... it may help a little to use a standard wallpaper at first, instead of the live wallpaper, just until the system has settled down.
All that said, I'm a huge fan of Core Droid HD, due to the animations and polished theme work done by Sergio76. It's an excellent build, and you can easily get the camcorder working with the system files fix included in the thread.
On a kind of related note, motoman234 has an excellent EVO Sense Black & Blue Remix build available, if the Desire HD Sense builds are too heavy for your needs.
Best to all,

Hi there,
Currently i'm using a SD-Android of MDJ.
Because of laggy animations i would like to update my current Build.
I've read through several NAND-Threads and nearly everyone says "fast fast fast".
This:
http://forum.xda-developers.com/showthread.php?t=877777 NAND looks very interesting, but after looking the Youtube-Video ( http://www.youtube.com/watch?v=4Ab0ztDxibo ) there i'm a little bit confused... The UI looks nice, but it's lagging as hell there! - OK, it's not like "Ok, i started the app, now i can make a coffee", but the animations arent smooth... There are SD-ROMS availible which are smoother!
Is this behavior normal?
Is there any fast Android ROM, SD, NAND, RAM, etc?!
The only thing i want is a Build, which is:
- nearly stable
- fast
- small (to maximise user storage, but i dont need that much, just a few apps and Mails!)
- without "Not working in this build"-Parts
Greetz and thx for helping!
Try Darkstone's SD-RAM build, it's really fast ...
I do know 2-3 SD-Roms which are very fast, but i want to get rid of WinMo, so i need another solution
SD-Roms are still "Workarounds till NAND"
Please post in the right section.
Darkstone's build seems to be the fastest at the moment, closely followed by Markinux's builds. MDJ's gingerbread builds are getting there. I find if I set the governor to OnDemand and OC to 1300MHZ, most NAND builds become as fast, if not faster than my benchmark Desire HD.
I was skeptical about NAND at first, I thought "what's the point"
BUT, all I can now is WOW! WOW!
NAND is 4 million times faster, smoother a a lot more than SD builds

Joined in 2008, 269 posts, yet you clearly post a question in the developers section, ignoring the Android question section
BTW, it depends if you want a sense build, non-sense, gingerbread, desire, desireHD etc etc. Each has it's positives and negatives. The slowest of the lot are the DesireHD builds.
Thx for your answers!
Sry for wrong-Posting the Thread, well i'm a little bit tired
Well... I do not need Sense, and i do not need Gingerbread, all i want is a fast Android build

Your given example NAND is experiment, testing NAND, Can't compare to the rest.
So is there no NAND availible for daily use?

I think you mean, stupid fast, I was using this before I went NAND, this was definitely faster than NAND builds.
This ROM is also stable enough for everyday use. If you are using Sd though, just install-backup-change-restore, is easy with titanium backup, just try a few ROMS until you find the one you like.
But i think NAND Roms do have a better battery life, right?
I've been using my NAND build on a regular basis since it came out. Haven't been back to WinMo since NAND was first offered. For me the fastest NAND ROMs are TyTung which I would rank as best as far as speed but its completely Stock. I've also tried cmylxgo and his is pretty speedy as time goes by...I'm actually using that one right now and its been running for 4 days with no issues. Got like 60+ apps installed and using ADW Launcher with a theme and loving this build. Might go back to Gingerbread tho after another week cause I have a problem staying on one ROM too long lol...
Haven't tried MDJ ROM but Im using his kernel and no data issues and market downloads are insane...may try his GB build out...
Also heard DarkStone build is crazy fast which is a plus too...
Have been using my HD2 1024 for past 3 days and love it. ATM have miui but its okay, dont like interface much. Tho I must say, every nand rom was laggy for me for first 5 minutes for sure. Then once you set it up, fix things up, do few restarts, the phone gets super fast. Like really fast. Unless you have ****ty laggy hd rom.
atm trying darkside rom
i am using mdj revolution hd sd version for over a month now.daily usage that is.i have a great battery life and its fast.i think its one of the best sd version.like the animations,recommend it.
Just installed darkside 5 mins ago. No lag at all so far.
:O Got rating of 4000 WTF :O
Thats on darkside nand rom
Hm...It seems everyone prefers another Build (and technique)
I've tried to setup setCPU on my current build... looks smoother till now, maybe i dont need to update that fast... maybe i'll wait for "the ultimate super fast and stable NAND ROM"

Thats not darkside, it's Darkstone1337.
#2
The build is called SuperNAND.
#3
It's an amazing testiment to the advancement of NAND/RAM developments by Darkstone1337, but not stable enough (yet) for daily use.
#4
To the original poster [infernalshade], I would recomend reading some posts 1st
That's where you're going to find the most indepth information on what's working & what's not in a certain build. Before you post, search search seach & search again. Most times it just takes some quick skimming thru all the pages to get the jist of things.
#5
Try it out. Sometimes stuff just works better on different phones, call it 'The Ghost In The Machine" or whatever. Besides that, who cares what anyone says if it doesn't suit you and your end needs

Most of the ROMs I've used are faster than SD builds. The Gingerbread ROMs are fast. The Gauner DesireHD is as fast as the SD builds of the same version of Android. But it does require getting through setup and a few reboots thereafter to smooth out to WP7 smoothness. However, every DesireHD ROM I've tried boots up super slow. That is where the SD builds excel above the ROMs.
its cm7.theres no stable build for cm7. its still laggy and buggy. cm6 will be less laggy and glitchy
So I have been searching the forum for a while but haven't been able to piece together a good answer from what I have been reading, so I decided to go ahead and ask. I know that these questions have been asked before, more or less, but at the rate development is going, and with the updated Android builds, I would guess things have changed even from 2-3 weeks ago, let alone 2-3 months.
What are the advantages of a NAND build (nowadays anyhow) over SD? Is it the speed?
Is battery life better on NAND or SD or it is really up to the kernel?
Are RAM editions somewhat speedier than their counterparts? if so, are they less stable or something than a regular NAND or SD version? I mean, if they are equally as stable, why isn't every developer doing RAM versions to get the most possible speed?
I know the speed of the SD card helps with SD versions to some extent. I bought a 16GB class 10 Wintec for that purpose, and it seems to do well. At that point, battery nonwithstanding, would be it worth it to go to a NAND build or would the speedy MicroSD make up most (if not all) the difference?
Thanks for the answers in advance. I just wanted to get a little bit of updated info from those in the know
While I am at it, another question to add to the list.
Does the underlying OS make a difference with the SD build? I know that Android should shut down and supersede the WM drivers, but would having WM7 over WM6.5 as the underlying build make any difference whatsoever to anything when booted into Android from SD?
thanks!
Main advantate of NAND is that you can replace SD card without turning off phone. And your build don't rely on speed of SD card. But due to small storage space, many builds still use SD which kinda defeats it's purpose.
Sent from my DL DesireZ 3.3 final using XDA App
No one has any idea on the other questions? Thanks for your input matejdo.
Again, some info is appreciated.
SD/RAM/NAND?????????????????????????/
I would really like these questions answered too.
I know that so far NAND is more complicated ....
with 2 or even 3 partitions, from EXT2/3/4, < who knows which is best.
And NAND is not as fast as RAM obv but is much safer in regards to corruption.
I have found SD builds to score higher in flops and quadrant than NAND however which is strange. SD is easier to copy to device, other than that im sure all custom roms have their issues. including screen light on lag.
i have tried and loved darkstone ram edition which was rapid but just not all there is you know what i mean, and now after giving up on dandiests desirez3.4/5 in nand and sd after too many lags, crashes and data drops etc im looking at MCCM HD V4 or MCCM GB1.8 SENSE GINGERBREAD as these seem to be the most stable build with all functioning functions but i shall soon see how they fair.........
.............................greatest respect goes to all devs for you efforts
we're nearly there!
but please any input regarding these questions would personally b appreciated!
Ok, here's my 10 cents. Some of this is debatable but these are pretty standard answers.

Battery life is typically better on NAND. Kernels can also make a difference.

Technically, RAM editions are faster but they are worse on battery life. Data stored in RAM requires constant power and does not survive a power cycle of the phone, therefore the data is stored typically to SD card, which also consumes more power.

Previous answer is why, more power consumption, data stored on SD.

They say NAND write operations take longer than an SD card but for the life of me I still find it faster when a ROM is running completely off NAND than off NAND and an SD-EXT partition. Or, NAND versus full-SD- there is a huge difference in responsiveness between read speeds. They are much faster on NAND than even a fast SD card.
Hope that helps...

It can be more complicated... until you do it once or twice and fully understand how it works. Now that this has all been out a while everything is starting to standardize and more and more ROM's are using the same partition layouts. From a performance perspective there really isn't anything noticeable between EXT 2/3/4.
Oh, most ROM's now also use CWM, which along with an SD-EXT partition can leave you with up to 7 different partitions on your device. Fortunately, you don't really have to manage any of them as the ROM's do all the work once you've set it up once.

This is due to a slower write speed of NAND storage versus SD storage. But, because the read speed of NAND storage is higher you still get an overall feel of greater responsiveness and speed even though the scores are lower. NAND ROM's are easier to backup and manage via the CWM aspect.

Possible problem may be higher amount of RAM needed. Especially sense builds would need a lot of RAM.
I have to disagree with a lot of what the post above mine said... The main difference between NAND and SD builds is with NAND builds you can use clockwork recovery, remove and replace your SD card while booted in android, and maybe a few other small improvement in stability and performance, but nothing too noticeable. Speed and battery life are about the same. You might get a little better battery life on standby with NAND. I generally got 3-5ma drain on standby with NAND, while I get 4-6ma on standby with SD. Speed and performance are pretty much the same because when you're running something with either type of build, it does it from RAM with either type of build. When an app or a process is running, it goes into ram, regardless of where the info was stored. NAND and SD are just the 2 options of where the data is stored when it's not being used by ram. Actually, the NAND in the HD2 can be slower than the NAND in good quality SD cards... but the random access speed is good in the HD2 NAND. But with a high quality SD card, you can get just as good random access speed with SD. That is what makes the performance difference with different SD cards... when the OS is trying to access small amounts of data or write small amounts of data, different SD cards will take different amounts of time to access... and the class rating of the card has nothing to do with that... in fact, class 2 cards tend to have better random access times than class 6 or 10.
But anyways, if you have a good SD card, performance and battery life are about the same... depending on the build of course. Desire HD builds tend to run a little better on NAND... but some recent SD DesireHD builds are good, too. AOSP and CM builds run pretty much the same off of SD and NAND as far as I can tell.
RAM builds work by loading more of the OS files into RAM at startup so that the random access speed of them is improved greatly, since RAM is the fastest memory and where any data is loaded to run anyways... it cuts down on the need to access the SD card for as many small system files, which improves performance and battery life in theory. The RAM is used anyways, so it doesn't use any more power keeping extra data in RAM, and since the SD card isn't accessed as much, it saves power there. But SD doesn't use much power anyways, so it's not really a noticeable power reduction. Also, RAM builds are still pretty experimental, and can have problems with data corruption... if any changes made to the os are not recorded to the SD, then if you lose power suddenly, there can be problems. Also, keeping all those system files in RAM causes you tohave less RAM available to run other apps and such... thats why there's no RAM builds for DesireHD builds, because there's not enough RAM. Personally, I never noticed too much of an increase in RAM builds performance compared to other AOSP SD builds like JDMS. Also, I'm not sure why, but I don't think RAM builds worked very good with NAND. But in theory, the system files in RAM is a good idea, especially for SD cards so it takes some stress off the SD cards. When running a build off SD, your accessing the SD to read and write system files while also accessing it as normal to run your apps or play your music or other data you have on SD. Keeping system files in RAM cuts down on the work the SD needs to do in the same way installing android to NAND does... then the SD is just used to access your media files or apps or data.
So in the end, it all depends on what you want from your phone... if you are not going to use winmo or wp7, and only use android, you might as well put android on nand, even if the improvement isn't that noticeable, because you can then use clockwork for easy updating or flashing roms, and you can change out your sd card, and there may be other small improvements. But if you still use winmo or wp7, then you have to decide if it's worth losing the ability to run more than one OS to give your android the added functionality of clockwork and other improvements. I use android on NAND for a month or so, but I didn't like how it turned my phone into just another android phone... it couldn't do anything that you couldn't do with a desire or evo or other android phone. But with the ability to run winmo or wp7 also, it's the only phone that can do it this well. When wp7 was released for the HD2, it was perfect for me because I wanted to try that OS out, and now I love that OS almost as much as android... I would have a hard time picking between the 2... luckily I don't have to. No other phone can run both of those OS's, either... I feel like I'm really making use of my HD2. If I just wanted android, I would've bought a native android phone from the beginning. But the great thing about the HD2 is no matter what OS you want, the HD2 can do it. People who want just android can make their HD2s almost like a native android phone now that it has clockwork recovery support. People who want 2 OS's can do that too. Android runs great from both SD and NAND... so use what works for you.
the battery life in android roms, is better than original windows mobile?
speed battery and efficiency are the main reasons
Yes it has a beter battery life (imo)
Ram is faster memory wich will make everything very fast, but you have to fuzz with Windows Mobile (?) to get there and that is what people dont like, the I/O on RAM is very fast, thats nice and makes quadrant scores very high
Class 10 card is good for SD versions, but imo that is very outdated, NAND is the way to go, like real Android devices loaded from the phone memory, not ram or sd, wich gives a beter battery life and fast speed (almost like stock) .. and also important , no fuzz with Windows Mobile.
And rest of the data wich isnt on your phone mem can be get of your SD card with a NAND version, cause the phone mem doesnt have rly that much space left after u installed Android on it (enough for enough apps though), class 10 mostly means a faster speed, so it will benefit you in some way

No offense at all, but I really tried to read your massive wall of text but I got lost after the first sentence.
I beleive that the custom android roms do last longer than original winmo. I love this 2.3.2 rom on my HD2. 2.3.2 on my gf's mytouch 4g last about 18 hours on moderate call/text/ use with overclocked on 1.3

for ex in win mobile, using the hd2 moderatly, how long the battery survive? and in android?
Wow! Lots of great info here!
I have been playing back and forth with different OS's and builds and SD builds and NAND builds etc. My phone is probably screaming at me to give it a break
As per responsiveness, the NAND builds (non-sense) seem to be a little snappier than the SD ones for me. The battery life seems about the same. Haven't had a problem with NAND space as I bought a US HD2 with 1 gig of ROM space, which is plenty for me. I haven't actually delved into the WM7 yet, but after reading this, I think I might give it a whirl and see what happens.
The biggest difference for me between the Android Nand/SD builds was the initial loading times. Which makes not that much of a difference because I tend not to turn off my phone anyhow.
The 2nd biggest difference is the wake from standby. On almost all the SD builds I tried, I would hit the hangup button, and the screen would come on in like 1/3-1/2 a second. If I accidentally hit it twice, I would have to wait 3-4 seconds for it to work properly again.... more presses seemed to do nothing. On a NAND build, it seems like the screen comes on instantly, and does not have the repress issue. But, then again, this is not a big issue for me at all.
The fastest build, by far, that I have tried so far is the Hyperdroid v5 build. It really does respond faster than almost anything I have put on the phone.
Thanks for all the answers people! It really helped to fill in the gaps in my admittedly shaky knowledge!

Yeah, sorry about that... I tend to try to fit too much info into a post all at once and I sometimes don't organize it well. I'll also ramble on sometimes to get everything out I'm trying to say and it ends up making the reader miss a lot of the important parts.

i understood it quite well..i think u have alot of valid points.. There arent big differences between sd/ram/nand...its a matter of choice imo..

if its on sd card it will still load into android after turning off everytime right? i dont want to see windows anymore at all

The main difference between NAND and SD builds is with NAND builds you can use clockwork recovery, remove and replace your SD card while booted in android, and maybe a few other small improvement in stability and performance, but nothing too noticeable. Speed and battery life are about the same.....

Thank you for your post it has the best thought out points for and against, and greatly helped me in deciding which build to go for.
Hey guys I know this question quite possibly gets asked all of the time. I'm looking for the fastest and most stable rom for my 32b.
Here is what I need to know.
Best rom, radio and spl combo.
I wouldnt mind it being cyanogen based as im a huge fan of the power control widget in the notifications bar and some of the options.
Doesnt matter to me what version is it, as long as its 2.1 or higher. Reason? App compatibility.
So please. Any suggestions will be greatly appreciated. thanks again and sorry for the "n00b" question.
I just put Frosense by Rushness on and it is the fastest I have ever used. I have ezTerry's non-engineered spl and the alternate radio which gives +14 MB RAM
Sent from my Frosense G1 using xda Premium
I am using Frosense by Rushness & i think it's fastest rom that i ever see!
I actually just installed cyanogenmod 5.0.8 with the 2708+ mod for it and its extremely fast. I'll have to make an nandroid backup and see what frosense is all about.
Anyone know rom witch i can run Angry Birds without "laggs"?
Try an older version. I personally do not play the game or care how it runs. My main concern is how to make my phone run well on a day to day basis.
Cyanogenmod with the 2708 radio, and swapper2 using a 64mb swap partition has proven to be the fastest yet for me. All of my apps work and although i had to downgrade zeam to make it work with Eclair, i'm still happy with it.
everything is snappy. My widgets work just fine and the overall experience and usability of my phone is what i would expect it to be.
I would love a froyo rom and i may try frosense in the future. for now im content with what i have.
Froyo for Trout is very fast.
If your looking for a super fast GB rom use mine. It has 60Mb of free space, aways 20MB or ram free. Look for Nomy's CM7.1 2.3.7 in the Dev fourm. There's no swap,or MTD. It's under 40MB Zipped. Hopefully will be under 40Mb unzipped

I would love to use GB. How does it rate in terms of speed and battery compared to eclair? I'm looking for the best overall experience.

So far the 5.0.8 2708 mod with the last bifftest kernel has been the best overall for me. Almosted tempted to try it on 6.1 to see if I have the same luck.

Frosense i used it and it's over.With the new release it will own the rest

Try Cyanogen 5.0.8 2708+
Aleks. Thats what im currently using with the updated biffmod kernel. Works great!
Wondering if the 6.1 2708+ would have the same success plus the little extra i like like notification bar power control and updated zeam by using froyo.
If i could get that and keep the same nice batterylife and speed of 5.0.8 2708+ i would be one happy camper
Still wouldnt mind a froyo+ rom. looks like when it comes to speed and stability its either going to be biffmod or froyobylaszlo. any thoughts?
xtreme-froyo-1.9.5-signed.zip
Google that rom or find Xtreme froyo, this ROM is best 2.2 I've found for G1...The battery drain is okay, in Biff it was faster, and in Ginger the battery was awful. I tried 2.1 ROMs but they seemed sluggish.
Seems everyone likes froyo by laszlo as the best feature/speed/battery balanced rom. does this do better?
never seen it here so i figured i may as well ask.
froyobylaszlo 5.2, spl latest, swap 128 +512 mb ext4 - my option
it seem to be fast!
What kernel? What compcache settings? Etc.
Sent from my HTC Magic using XDA App
Just curious. Since i get great results (performance is satisfactory and battery life is great) with the biffmod kernel over the ezgb kernel in cm5, couldn't the same be said for almost any other rom so long as i use that kernel? The only downside ive had with said kernel is i cannot take 3mp pictures. The camera is sort've crap anyway so i can live with 2mp.
The reason i ask is because i would like to bump it up to froyo but would like comparable performance with about the same battery. Our am i just living a pipe dream?
What I need out of my G1 is battery life. I pretty much use it only for email (wifi and mobile). I've tried pretty much every rom out there for G1, even went all the way back to Donut assuming its battery needs would be minimal. I saw ezTerry's gingerbread and thought, hmm, I'll install it just to see what its like. I assumed it would be very hungry and I'd go back to something lighter. I was very pleasantly surprised.
I've had it running for about a week and a half now. I have wifi on all the time, and the stock email client is setup with a fairly busy exchange server account (push). The gmail client is also setup with my main gmail account.
I am averaging 30 hours like this between charges.
I should say that I do not do alot of voice, perhaps 20-30 minutes per day (on a busy day), so this is strictly an internet device for me, no games, not alot of surfing.
Hi. I know that it is a noob question, but I am wondering why JB builds are so laggy. They should be smooth. I don't mean performance, because that one is great, but overall interface is "heavy" and laggy. Eg. statusbar line (this one we slide up and down), switching windows etc. Scrolling is great so why these stuff aren't so? And MIUI Jellybean: I know MIUI as the smoothiest roms, but JB edition is a nightmare. I understand that these are early builds, but not so early :/
Did you tried the NativeSD releases or the NAND ones? Which class does your SD Card have?
I've tried both of them. My SDs are 4class and 2class, which 2class (about 18MB/s read in Low Level Benchmark in Flash Memory Toolkit, and about 1.5ms access time) is better than 4class, I think 4c is just dead. And transffers and I/O is perfect, but animations are sharp, like the GPU was weak, but it shouldn't be SO weak...

I agree with him, and it's not a matter of NativeSD or NAND. Jelly Bean just doesn't feel as smooth as Ice Cream Sandwich, even though it has hardware acceleration. That's why I'm sticking to ICS atm.
i really dont know what yall use your phones for but i use the roms in my sig
and they are smooth and fast for my everyday use

Well admittedly I only have experience with one JB ROM on my HD2 (the one in my signature), doesn't feel laggy at all to me, in fact it's pretty zippy, and consistently so. I have OS on NAND and programs on ext (class 10 SD card). It's a rather mature version. I read that MIUI is also no slouch. Could you possibly have had a faulty install?
I have the some problem with the lag. I use kovjanos' PA ROM with the pure PA framework. Everything is smooth and fast except for the window and framework animations. When I open an app the opening animation lags and if I pull down the notification drawer, it seems like the drag bar "stays behind my finger" so it follows my movement really slow. The usual display-off animation doesn't work either. I tried different 4.1.2 ROMs and had the same thing everywhere, no matter NAND, NativeSD, or DataOnExt.
I tried the evervolv 4.2.1 as well and it works perfectly, all animations are smooth without any lag.
I think it might depend on whether the ROM is compiled from source and with which device tree, or whether it is ported from an other device and which ROM was used as a base.
