How much internal memory do you have left? - Fascinate General

I have voodoo (dirrks) non overclocked, don't have a ton of apps installed but have just over 700mb free internally. I know its because of the voodoo partition but is there some way to relocate some things? Pretty sure my browser cache is set to external...
Feel like I'm gonna run out soon

i have 1.3 gigs

Voodoo should not take up a significant amount of extra space. The old ext2 lagfix did because it basically created a virtual partition within a partition but Voodoo doesn't require any additional space (beyond maybe a few meg for files).

Actually, about 200mb, give or take.

Yeah out of the box I believe the internal storage is 1.52GB, with voodoo it drops to 1.31GB. According to appbrain I have 180 apps installed taking up 425mb. So according to the stock task manager I'm using 672mb out of 1.31GB [basically half]. Im not really in danger of running out of space anytime soon

Thanks adrynalyne - I stand corrected.

Dang just found out that nfs shift is taking up 100 mb, 100! But is there a way to just relocate this to the memory card?

Available Memory

So when im not running anything, when i open Advanced Task Killer it has like 125M is this right???
So what the other 387MB doing?
what I see
when I 1st start I have about 230MB, after a few minutes it goes down to about 90mb...without opening anything...seems many programs on the Samsung "open" by themselves...also, I see that the CPU goes down to about 100Mhz so I keep it at 1000Mhz with setcpu....plus deleted many Samsung apps(about 30MB)...helps with the lag...
Don't worry so much about it. This isn't windows, you don't need to worry about free RAM. Android will kill tasks as needed to free ram when it needs to. Some of that is likely used for disk cache as well. That will also be released as needed. Let the OS do its job, it's quite good at it..
Killing some of the bloatware will help as well, but you need root.
I also think that this phone, like the G1, has some of the speced 512M ram dedicated to the camera, GPU, and other stuff. In the terminal, free shows about 388M as total ram.
is it a good to create a swap partition on the SD card?
Why on earth would you want swap with this much ram? You likely can, with root and swapper, but why? This phone doesn't need it like the G1 did. Swap could help keep more apps open in the background, but there are already a lot of them there. I don't see any benefit to swap right now. What isn't working for you that you think is related to low ram?

As with the nexus one, not all 512mb can be addressed by the system right off the bat; we may need to wait until a newer kernel comes out

Swap File

Most Say that a swap file doesn't make Much of a Difference, From personal experience I would have to disagree
Running free in the terminal on a normal nor swap enabled day I would have 22 - 200 free, this is running no programs, and 3 email accounts
Recently I created and enabled a 512MB swap on my SD, against my better judgment of swapping on solid state..
This has had Drastic improvement in performance let alone free not showing 3916 free in mem and 14424 used on the swap, My shift is alot more fluid and responsive,
Your results may vary but i figured i would share my results
Im running scarystable comp cache 18%, vm heap 48m on CM7 nightly 238
again I don't claim to know anything more then the next guy Just sharing my results
Give me about 15 minutes and you can have these types of stats when you type free in terminal. It does help, regardless of what others have said. And scary kernel will work.

I love it, Now my only worry it the wear on my SDcard, but I figure aslong as I delete and create the Swap file once in a while it will ware evenly, I just never expected this kind of gain from it.
I will admit 512 may be overkill but it sounded nice
Thanks for your results!
The problem with swap files/partitions is they're slower then ram so you need to buy the highest class sdcard your device can handle to have anything resembling a positive effect and they'll destroy your sdcard. Plus unless you have a script or app to manage swap its a pain to have to disable and re-enable swap when attaching to your pc through usb.
With our devices having 512 ram and something like V6Supercharger with compcache disabled I've found I always have more then enough free ram for pretty much anything.

The data rate of a class 10 sdcard is 10MB/s. DDR-200 which is the oldest and slowest DDR ram is 1600MB/s. Swap is slow regardless whether its a file or a partition.

Yes, but a swap partition can -not- increase the physical read/write speed of the sdcard which is the point I'm making. Is swap file slower then a partition? Yes I never argued that. My argument is swap in general is slow.

If your here to use, test swap, provide your results ect fine. If your here to bash swap, then please stfu and go away. We don't need negativity in these forums. do you even know what swappiness is or how to set it?
Swap
Swap is not meant nor does it truly need to be fast, From my understanding it takes whats not being used from ram and "swaps" it to disk to free up ram for programs that require the speed, It is not a replacement for direct ram.
None the less I thank sparksco for his Post and will be trying it out later in much anticipation

Swap file is useless and slows your phone down. Just like a pagefile on windows.
"disk" is ALWAYS slower than "RAM"

Does MTD/Yaffs2 perform better than BML/Rfs,Ext4?

By now maybe there are some available performance results, especially since it's possible to run the same rom with different file systems.
I haven't seen much discussion about the performance aspects even in theory.
Is yaffs2 faster? Is it more stable or less likely to corrupt files? Does it result in more disk writes? Is it harder on the storage medium?
So beyond the fact that MTD/YAFFS2 is more mainstream and will make CM easier to keep up with what, if any are the performance benefits of the filesystem itself? Especially for people who may never go to CM or won't for months.
Oh, last question: MTD allows more storage in the /data folder if I understand correctly. How much more though? What is the /data size under BML and how large can it get under MTD? And what performance benefit is there from that?
More stable, faster, less writes, easier on disk, open source, dev customizable for partition sizes (not just data)...

I switched over to MTD yesterday and so far my phone is running fine. The switch took half an hour and I notice a little less lag with
certain apps.
IMO, you need to try it for yourself and see if you like it.

1. From my own personal experiences, yes it contains a quicker response in areas in which it is needed, more of a smooth user experience. I've not yet seen someone complain about a clunkiness due to our new partition configuration. Yes it is more than stable, data corruption on MTD/yaffs2 is unheard of, very unlikely as it doesn't just randomly occur or nowhere as often as it can on EXT4, it doesn't mean that if you do something like OC to a high frequency that it cannot happen. That's always is and always will be subject to how you run your device. And no, it is more meant for flash based devices which we in essence are. It's a ways smoother and reads and writes better to our nand.
2. To a normal user, in all honesty, it's something new. The benefits are the increase in space of data. 689 mb to be exact, although some of that space is always being used from the getgo. Being that there are now stock boot.imgs any user can go to MTD and not truly have a need to go back to BML or the constant fear of having to Odin for those who are iffy on it and not lose out on the stock feel, they've a choice between AOSP as well as StockWiz.
3. 689 mb MTD compared to about 200ish BML, or less in the data. And you've got to take space from the others to allocate it in the longer run of things. It doesn't stunt or skyrocket performance, it's independent of it.
Let me know if I answered your questions at all lol. I was vague as usual.
I've battery pulled dozens of times on yaffs2 with no data corruption. no such luck on ext4
Sent from my SPH-D700 using xda premium
I've not noticed one iota of difference between RFS, ext4 and now yaffs2 in real world usage, so all I can go on are the benchmarks I've run.
In my testing synthetic disk benchmarks have shown yaffs2 to perform about the same as RFS. ext4 is only faster when mounted with the unsafe, data-corrupting 'noauto_da_alloc' option. Without that options, it performs about the the same as RFS too.
yaffs2 is a win for all of the reasons marcusant listed aside from (IMO) performance.

You can thank the 'noauto_da_alloc' option for that. In all of the documentation I've found regarding ext4, it explicitly warned that if you use that option you must have battery backup for your disk devices or you will experience zero length files in the case of power loss.
Whoever first discovered that tweak on ext4 and convinced everyone to use should be smacked over the head a few times.

When I was first making my kernel I noticed that my ROM running ext4 would only score 1700 in Quadrant while other ext4 ROMs scored 2300. It turned out to be the 'noauto_da_alloc' option that provided that instant 700 point boost. I also experimented with jourmaling and found the difference it made very small - at least in quadrant scores. The 'noauto_da_alloc' option leads to zero length files on power loss, regardless of whether or not journaling is on.
Oh, and I think I found the person who introduced this to everyone. It was supercurio.
I have to say I find this thread extremely informative.
Because of rfs/ext4, I expect there to be some form of tradeoff going between file systems. I'm a lot less worried about that now.
Thanks a lot all.
My understanding from the answers I've seen is that quadrant scores are about the same between rfs and yaffs2 and there are almost no real-world performance issues either way, except that it will take longer before you have to begin moving apps to sd storage.
If that's right, thanks for making it very easy to get that info.

Ouch!...LOL! And as quickly as I could re-enable journaling I did. Did not notice any performance difference. Now we have MTD!
Another thing, the extra space on the /data partition only comes for roms built for MTD, correct?
Until TW roms are built from the ground up with MTD, rather than porting them across, that benefit will not apply?
Also can someone explain in more detail where this extra memory is coming from? Do BML filesystems just waste 400 megs or so of storage space, or is something being compressed or removed to get this extra storage?

This extra space is on every MTD ROM out. The space won't change whether the ROM is intentionaly built on MTD or not. The extra space on BML is taken by /cache which is reduced to 25MB or so. /cache is really only used by market(for large app downloads) and by OTA updates(which we'll only see 1 more).

2nd system from webtop partition

I have noticed that the Atrix 2 is capable of running 2nd system from the webtop partition as a form of dual boot, I was wondering if there is any chance of a DEV implementing this into a recovery image, The Atrix 2 uses safestrap that has 2nd system support, was just wondering if it was possible to do this on the Atrix.
Many thanks

This would be awesome... I don't even have anything in the webtop partition at the moment... and the stupid hardware reserves 200mb of the ram for it anyways... might as well get SOME use out of it!
I'm going to look into it , I have seen it being done on the Razr , I imagine it works in a similar way to the sdcard dualboot just with the mount points pointed at the osh partition.

Call me crazy but If the hardware is reserving 200mb of ram for webtop, Wouldnt that be a matter of just editing memory reference.. or would that require the kernel source?
I recall when I had a galaxy 7500GT it had 98 MB of ram and some dev had tailored a kernel to use the 4 mb of video ram for system memory ( at the cost of 3d acceleration) to bump the phone to 102 .. not a huge difference but it helped.
being able to use /osh to boot maybe a super stripped down blur rom for camera/camcorder ect stuff would be nice though.

I was under the impression that the 200mb of ram is reserved for the graphics and frame buffers, technically no webtop processes that consume RAM are started unless the device has been docked.

I think you are right, he might be thinking on the /osh part.
Imo left the system as it is would be better, we all can dual boot from sd and thats good enough. If u want to use use webtop left over space cos of cm7-9-10 then best thing would be to decrease the sise of partition as much as possible. No partition table change no sydtem level mofigications required and u dont have to do any thing especial every time u flash. Correct me if i am wrong

If I didn't need my phone for work, I'd try the sdcard method and symlink to stuff I've flashed into the webtop partition.

High RAM usage

Hi,
I noticed that ram usage on galaxy s4 is very high even when all of the apps are closed. I have used task manager to close all of the apps and then cleared the memory but there was still about 1.05GB of ram used. I don't know if this is normal since I haven't been using android phone for 2 years. Can somebody tell me if this is normal and why? If not what can I do to fix it? Thanks!
Sent from my GT-I9505 using xda app-developers app
its normal for s4... some stock apps are being cached in memory for faster operations
unused ram is wasted ram. If an app needs extra space, something will be automatically killed to make that space.

all of this is true... also keep in mind, the gpu requires slightly more ram because of the 1080p resolution.
Ok. Thank you all for the help
This is the problem of Sammy ROMs, the only way to fix it is to... wait for a Custom ROM and Flash it
this is normal on SGS4 .
Reasons of that are mainly GPU and HQ resolution , cached services and process, and even more if you are using the included extra features (S-voice, NFC ...)
But the SGS4 come with 2 gb of RAM ! you still get like 800 free mb of memory that is good enough for all you needs ))
Personally when I close all apps i get 0.91 gb used memry and 0.9bg free memory
