I have been using lagfix - ext4 since eclair and I was convinced of its benefit.
BUT recently I discovered it may not be such a good idea after all on froyo (v2.2.1). Why?
IT WILL LAG much more than RFS not at the beginning but at a few days into use/uptime later.
I only realised this after converting all my partitions back to RFS. After boot, I can't really tell the difference betw. RFS and ext4 smoothness (both are very smooth). But after 48-50 hours uptime later, with ext4 lagfix, I realised that free RAM seldom goes above 50MB and there is always a constant heavy cpu usage by kswap0 process everytime I use the phone. With RFS only, the free RAM varies up to 65Mb and the kswap0 cpu usage isnt as high as ext4 (i.e. there is still some lull period where kswap0 is not constantly hogging cpu). Of course RFS still slows down (but tolerable) overtime but not as bad as ext4.
I'm suspecting that the ext4 filesystem is hogging or leaking memory leading to smaller pool of useable RAM. This is causing the constant swap of dormant apps out of memory thus contributing to the lag. I am kind of convinced that the hated LAG is caused by this kswap0 process. (This kswap0 process usually has low usage just after boot thus the great speed but as time goes on it deteriorates)
Anyone has the same experience or want to comment on this?
(I am using doc rom 9.6.6 + speedmod k13d kernel)
I never had lag with RFS on 2.2 and above, but ive been running lagfix (ext 2/4) since the day i got my phone,
i do find that after a long time RAM gets reduced alot, but if my phones been running for 48+ hours, (which is rare cause i always flashing) i do a reboot to spice up my life a little lol
you should just do that too.
ext4 isnt harmful to the phone in the same sense as lets say...... overclocking CPU.
lagfixes only cause problems, like file corruption (when flashing without disabling) but a re-partition in odin fixes that up
Are there any available tweaks of RAM, Swap, Zipalign, IPv6, kernel, battery, internet, sdcard, gpu or sysctl for Froyo? It would be a great thing because my opinion is that Froyo better fits our X8, especially Floyo 0.30 that I'm using for three months day to day without reboot crash or laging. Thanks
Which better in sd memory cards
Kingstone 32gb class 10 OR
G- Skill 32gb class 10

Ok Thank u very much but actually the link helped me in knowing that class 4 may be better than 10 in some cases but it did not help in the comparison between g-skill and kingstone .. also i want the sd card to do the trick of increasing ram by rooting .. because the performance of the ram is terrible due to installing a lot of app;ications and games
ok can we add in the comparison SanDisk 32GB Micro SD Ultra Mode
so the will be what should i buy ?!!!!
1- SanDisk 32GB Micro SD Ultra Mode
2- Kingston 32gb class 10
3- G-skill 32gb class 10
No answer till know ?!!!!!!!!!!!!!!1

I'd got for kingston if you want stability, sandisk is kinda good with speeds, don't know about G-skill

BUT if i were you, I wouldn't use my sdcard to increase my memory.1 GB is enough, actually more than enough.You may be wanting more memory due to stock ROM using too much RAM, but android is designed to use lots of RAM.For example, android will cache the apps you use oftenly in your RAM so that they'll launch faster and you will same some battery if you launch them often in short amount of time.
For the RAM performance, I think we've got ddr2 1066 (not sure), which is fast enough as its even faster than my PC's (ddr2 800).IF you haven't cleaned your ROM by removing bloatwares (most of the apps with LGE name in it are bloatwares), your phone will lag and yes, your RAM will slow down.After I removed all the bloatwares, I freed around 150 - 200 mb RAM and my phone became smoother.So you should try this before you kill your sd card for a little bit of more RAM.
NEVER use sd card to increase your RAM, It will kill it easly and your phone won't be fast at all.RAM is a lot of faster than a class 10 sd card, your phone could only use your SD card to store inactive **** inside that SD card and even then your phone will be sluggish, especially when your freeing up some RAM.This can be done by launching a game, android would push inactive apps, caches into your SD card, thus making your RAM do more work while transfering data over to sd card and slow down launch time.That could also slow down games which require a lot of RAM speed.Ironman 3 for example, you keep switching between environments which requires textures to be replaced inside your RAM, in that kind of case you'd experience lots of lags.In brightest situation, your phone won't lag as much but you won't get any performance improvements either (perhaps a little until you launch apps) and your BATTERY will deplete like hell.
Your sd card won't last for long no matter what you purchase, all flash memories have a limited write-read cycles, and using it as a RAM would do a lot of r/w cycles, thus resulting in very short lifespan.Google dead sd cards caused by that RAM expanding method, you'll find a lot of dead sd card complaints.
Source : I used such method to increase my old phone's little ram (290 mb).Which resulted in an even slower phone, with lots of lagspikes and slower UI.

That is . Using sd as a ram will not speed my phone also it will consume battery " this is the biggest problem " so tell me how to speed up my phone , minimize freeze as i have more than 40 apps and The Dark Knight rises , Need for Speed and this games can not be played well and a have from 150 to 200 mb of ram free only !!!!!!!!!!! i don't know why . also i usually kill all apps that still worked and this don't do anything

150-200MB free is more than enough. Android runs on a *Nix base - it is designed to use all the memory it can and will free up memory as needed. "Free memory is wasted memory". Lagging is due to the GPU, CPU speeds etc - lots of people have problems with playing games on this device.

How empty is your internal SD card? Ever tried V6 supercharger script? What kernel are you using (I'd recommend eternityproject kernel)?
Your cpu shouldn't have any difficulties loading chrome, don't think its related to RAM, perhaps your having I/O lags.

I currently have NFS, the dark knight rises, real racing 3 and dungeon hunter 4, a few more apps that consume 100 - 200 mb internal memory and around 20 more small games.I'm experiencing no lags in any games except the dark knight rises (thanks to gameloft...) and dungeon hunter doesn't lag in normal visual settings.
I'm using eternity project kernel and V6 supercharger script to manage my RAM.
NEVER use a task killer in this device, Use an autoruns manager (such as gemini app manager) to stop apps from runing in background, consuming RAM & cpu.That helped me smoothen my phone when I had lags back in the day.

Le Kingston because they produce the highest quality SD cards. I never had any problems with any Kingston product, be it a USB flash drive or microSD.
The class 1-10 also matters, get a high class kingston microSD card.
Hello!
I've been noticing that my Optimus 2X is getting more lag spikes everyday, and today I ran a Benchmark on the write and read speed of my internal memory. Results?
- Write speed: 1.72MB/s
- Read speed: 2.82MB/s
Are these normal speed levels for the flash memory?
Thanks in advance.

i dont known. Run Antutu Benchmark Sd card IO -INTERNAL- . in write:150 and in read:189
if you points are low of this maybe your adjust buffer card with ROM TOOLBOX PRO:512kb-1024kb-2048kb is best
I got my Mi5 from Gearbest last year, which started to lag after a short period of time independent from the ROM I used:
I think I started out with MIUI 8.1.2.0 .
After a while I upgraded to the first Nougat based MIUI version.
I moved on to a CM based custom ROM (RR 5.8.5).
Now I'm on LineageOS 15.1.
With all these ROMs the phone was smooth in the beginning but started to lag significantly over time. It's really bad when using Second Space respectively switching to another user (vanilla Android version of Second Space). I have ~100 apps installed and mirrored the setup on my old phone (ZUK Z1) which doesn't lag at all.
I find it really hard to isolate the issue but after using SD Card Test I am pretty sure there's some issue with the internal SD card.
The storage is supposed to get sequential read speeds of over 300-400 MB/s and write speeds of at least 100 MB/s.
The benchmark test however starts out at around 30-40 MB/s and then continously drops until it goes to under 10 MB/s.
Interestingly if I use fstrim before the benchmark, it starts out at over 100 MB/s - but then drops down again after some time.
Does anyone have a clue what's wrong with my device? Is there any way to fix this?
Same here. It's difficult to track it down. It needs logging and accessing behaviors, ram usages, etc.
@NikitoGR What are you results with SD Card Test? I edited the OP.
