A2SD + data = very slow? - Legend General

Hi,
my /data partition is nearly full so I thought about using data2ext. I read the code which is used by data2ext and decided to try it with A2SD and simply move /data/data to SD and create a symlink.
This also worked but the performance dropped significantly. Android and Apps started much slower. I had lags everytime I saved/changed something. I read that data2ext should boost the perfomance so I'm a bit confused. Why is my performance so bad? Is this because I symlinked or what? Is it possible to get much better performance with the real data2ext?
I use a Kingston 16GB class 4 SD card (benchmark on windows said 14MB/s read and 0.7ms seek) with ext2 (formated like recommended in data2ext thread).

You should only be using data2sd and the performance depends greatly on the speed of your SD card.

Why would you use data2ext and a2sd at the same time? It does not make sense...If you have a fast SD, data2ext is a good way...but it has to be genuinly fast, not just high class

I didn't say I use both at the same time. I use A2SD and moved /data/data to SD.
A really fast SD card is expensive so I think moving /data/data to SD is not an option for most people. There seems to be no cheap way for me at the moment.

8gb class 6 works fine for me.

I've read some SD card tests and these classes seem not to be riliable. For example my old 8gb class 2 is faster than my new 16gb class 4.

I'm using a 32gb class 2 and I noticed a significant improvement however my quadrant score barely changed

Do you know the exact name of your card?

have you tried this? i'm using 3072, cl6 transcend, darktremor data2sd (comes with his a2sd mod, still in beta but i find it more stable than --with all due respect-- TGF's version)

Just tried data2sd from A2SD. At first it seemed to delete my system apps (contacts, mms, calendar...). After a second reboot most of them were there again.
But the performance was still bad.

Performance is horrible

I recently setup apps2sd on my g1 with 1.5. I also use swapper and since I setup apps2sd, performance has been horrendous with or without swap on. Has anyone else experienced this? Is there a fix? Is my card just too slow? I don't know what class it is. Thanks for the advice
if your card doesn't have a 6 on it....its too slow.
did you buy a new card other than the one the G1 came with?
My apps are a little slower to startup after apps2sd but I figure it's worth it to have 100 X's more capacity.
It's not the stock card and I'm assuming it's not a class 6. However, I went back to using stock home instead of openhome and performance increased dramatically. Apparently openhome uses too much memory and causes other apps to swap to the same card it pulls apps from.

I'm tired of repeating that SD classes are only a rating for minimum sustained write speed. Maximum speeds are usually significantly higher, and vary from card to card based on the size of the file written.
Right, but if you make one that qualifies as a class 6, you wouldn't write a 2 on it unless you're a moron and want to undervalue it.

Did you use the JF1.5 Lucid modded one? try not moving the data/cache to sd. That was the problem i was having. When i moved it over, it was verrrry sluggish.

Try DXtop instead of openhome.
yes, im using JF but i dont think I copied over any apps or cache. performance is slightly better since I upgraded and wiped but still doesn't feel like what it should be. maybe I will buy a new card

[Q] Increase RAM with flash memory on defy

hello,
im using Motorola Defy MB525 with cm9 4.0.3
my q is, can I somehow increase the RAM with the sdcard memory (like create something like virtual RAM or something like that) to improve my phone performance ?
it preety slow because it still Beta and i want it to be fast as cm7 so i thoght it may help.
anybody tried it before ?
You can do it by swap, but you need really good sd-card (class 8 or 10), because it can slow down your phone.
Don't you have enough ram?

unfortunatly, i think that its the only way to speed up my phone, becuase i wont take the risk with oc above 1000Mhz
its this or wait till cm9 will be official for defy and hope it will be faster, one of the two.
+1 to the idea was thinking about it the other day
Would a 32gb class 10 work and partition a gb or two? It is complete overkill to the size of ram but I think a gb would be quicker than our 500mb as system steals about 250-300 minimum
teamwork makes the dream work
If someone can do this with a 32 GB class 10, can you please share with us ? I am very interested. Thanks!
We cant do swap... our kernels dont suport it...

now cm7 can swap
More and more ROMs support swap, but unless you are willing to sacrifice a good Class 10 card for it, most people don't want to use it. Because SD and NAND are not meant to be written and read from as much as RAM, it can break down.
Use CM10 ROMs or GB roms, they are much superior to ICS in memory management imho.
I have teh same problen, not enough RAM in CM7 Defy.
It can slow the phone.
can i use some memory swap with my 32gb c10 card?
Or i use an memory killer, like CleanMaster?

I recomended use memory killer, because you can screw up 32gb 10 card (c10 cards are expensive).

[Q] SD Booster

I run Mirage on an Sandisk SD Card with Supercharger V6. Runs well.
I stumbled upon a program SD Booster which can be seen here :
https://market.android.com/details?...wsMSwxLDIxMiwiZGUubWVocm1hbm4uc2Rib29zdGVyIl0.
Has anyone tinkered around with this app to see what setting might improve performance?
Tried it back when I was running CM7 nightlies from SD card, circa 253. Didn't experience any discernable boost. As I understand, supposed to hype card write speed; can't fathom how tis done. I'd vote "not worth it".

Swap file.

I've read about this thread made by CarlDeanCatabay which discussed how we could increase our ram using the swap file thing.
I'm just curious if I could somehow do this with a class 4 sd card?
And how does it "degrade" sd card life? What would happen to my sd card?
Sorry. Just a noob. TIA!

sure it degrades ur card life bro
the sd card wont withstand that many read/write cycles
moreover using a class 4 card will affect the speed too
my suggestion is that you dont do it
But u can always try nd see for it urself

You won't gain much performance benefits using a class 4 card and its life will degrade too but anyhow if you just want to try it i would suggest that you download the app - 'swapper' from market - it provides an easy to use interface and trouble free swapping instantly . The way i do it is to turn swap on while using heavy games or the like and disabling it rest of the time
Thanks for the reply guys!

ROEHSOFT RAM Expander (SWAP)

Does this work as good as it says?

its good for gaming and multitask
and good for xperia play with 512 mb ram you try it good

There are some benefits to SWAP yes, however using your MicroSD as RAM is far far slower than using actual RAM - so some things can play a little badly with it.
It also isn't a healthy thing to use when it comes to prolonging the lifespan of your MicroSD card as its using all those writes at an almost constant rate.
That being said though, enabling a SWAP partition on your MicroSD card is a somewhat easy thing to do and there are loads of other apps that will do this for free for you. I would not pay for this.
me tried in all roms me use my memory class 10 and good swap for me

So what your saying is it would let me have more multitasking but at the same time it would be slower.
First here is how to do that for free.

And yes I use that method, for me my Neo2Play gained some speed, less lags. But there is but, best is when used with fast card. I have 32GB class 10, on my old class 2 it wasn't so impressive.
Works great for me with 1105 MB swap RAM on Atomic GB 7.0.(2.3.7) Especially when using it with RAM Manager Pro on Hard Multitasking setting.

hehe
This sounds cool
amazing
