what about this on hero?
hyyp://forum.xda-developers.com/showthread.php?t=637419
cheers,

pushed it, booted, logcat stops after a few seconds, then nothing for ten minutes...
For this to stand any chance of working you must be using a 2.1 ROM.
I pushed this to my hero running VANILLAIN 1.1 the phone does manage to boot up but I got a whole lot of force closes including (most unfortunately) the main phone software which continually FC'd and reloaded making the system very slow. Despite this, I managed to run linpack and got a return of over 3 mflops so the JIT is clearly running but untill the phone FC is solved clearly it is useless! This will have to be something one of the DEVs looks at. It would be worth others running 2.1 ROMS trying this out also.
I will continue to experiment!

Still can't get this to work correctly. Vanillain loads correctly but com.android.phone stops working unexpectedly every time repeatedly. However I have managed to get 3.633 Mflops/s in Linpack which is a vast improvement on the standard benchmark! If the devs can implement this to work without the FC of the phone then we will have android 2.1 running very smoothly indeed!
Pushed it to VANILLAIN 1.1. Managed to get 3.5Mflops/s (Linpack) and 283 Total CPU Score (Benchmark).
I'm going to use this daily and see if I'm getting any problems. Working fine so far with no FC.

sounds fantastic
what about the feeled speed(navigating and so on)?
I tried with kagudroid (1.2.2) but have many FC on principal apps and phone was useless... now i try with vanillain 1.1

Hi.
How did you do it ? The long instruction from the thread, or did you just push it ??
Rgds Gtot
Yeah, with vanillain 1.1 works very well
With linpack :
before : 2.102 Mflops/s
after : 3.3 or 3.4 Mflops/s
Really a nice performance boost and no fc or crash.
Follow the instruction of topic linked by spania.
Hi @all,
I just flashed the Vanillain 1.1 and tried to enable jit.
The problem I have is, that it does not found su like its said in the jit installation tutorial. But the file exists in the /system/bin.
Do I have to use absolute paths or is there something wrong in my system?
Thanks
Just tried it on CKDroid 1.6b.
With Root Explorer I simply replaced the libdvm.so and gave the file the same permissions as the original file.
Reboot, then the figures :
Before : 2.195 Mflop, 2.47s
After : 3.265 Mflop, 1.68s
Did not extensive tests, but i could not see overall speed improvement. Maybe should I test further.

I have done exactly the same on my Hero running Villain 3.0. When the phone has rebooted, everything starts up right, and i can see it receives new messages, but i can't unlock the lockscreen. It looks like the screen just freezes.
Any ideas ?

Update: After some reboots, i finally got in. It looks like everything works, except for sliding between homescreens (Sense FC). Benchmarking went from 145 to 278 and linpack went from 2.28 to 3.38 BUT i can't feel any difference.

Well mine is very stable and has gone from 2.2 to 3.2. However it isn't noticeable faster to use, will see after more testing!

Check internet browsing. blazing fast for me. Overall still a bit of imrpovement in application starting and running, but of course not in 3D graphics. But this is ovious.
JIT accelerates execution of code. internet browsing benefits a lot from my experience.

The new version of linpack has changed the measurement from a total of 200x200 to 500x500(don't know exactly what these numbers represent,sorry,but they are some kind of calculations I think).They did that to increase the precision in CPU processing power measurement because newer devices with powerful CPUs got inaccurate results in like 0,15 seconds.
Hope I helped!
oXbench is alot better tbh

tks allot guys ,i was just wondering...my phone is very responsive and it was jut a question of timing...25-30+ seconds seeing 1.4,1.3 ......
I managed to successfully run LagFix V1 so I can't remember exactly what the error message was, but when I tried to run V2 it repeatedly failed. Each time it was either a message stating that there wasn't enough memory on my phone (false) or that it could not create the path to make the LagFix. V1 worked swimmingly so I don't have any complaints on that end, but ideally I'd like to have applied V2 to my phone. Any suggestions as to how I can go about getting V2 to work on my Fascinate?

from what i've read.. that the lag fix doesnt really do anything besides boost your quantum scores... and that there is going to be a real lag fix coming down the road... since switching from tw to launcher pro and getting rid of all of the vz bloat... my phone runs 100% better than it did.
Just as it looks like. I have a Samsung Vibrant with Nero 2.2. Watchdog reports kswapd0 routinely sucking 50% or more of my CPU with both the kernel Nero comes with and Voodoo. What would cause this and how can I fix it?
Sent from my SGH-T959 using XDA App
Would love to see a response to this as I am having the same issue. Its eating up battery life.
Hmmm it might be the kernel
Sent from my GT-I9000 using XDA App
I also had this - huge slowdowns, phone always hot, plenty of Watchdog alerts. Few different kernels, don't recall all that I tried. I can tell you that it doesn't happen anymore on Blackhole 1.1 w/ JK6 modem and "Eugene's B series #20 kernel." I haven't been keeping up lately, that's quoted straight from ROM Manager.
I am having the same problem. I read that it is to do with the Linux base which voodoo uses. I am using voodoo kernel but not really sure how to go about replacing it with something as good but without this battery raping problem.

having the same problem with Darky rom on the Captivate and speedmod kernel
is this process just present in all ext4 enabled kernels?

it may be present, but on my voodoo its doing nothing more than what it should.
theres nothing thats making any service act up, it might be the kernel.
change to voodoo, its da best.
I'm on a captivate using a voodoo kernel having the same problems, this definitely seems to be a galaxy s problem. I'm read that changing the kernel paging size with the touch command to 10 instead of default 100 can help prevent this, I saw that solution on a centos forum though so it may or may not apply to android. I might try it out later after I take a backup. this post might be talking about the same thing, though the poster claims to not be a kernel hacker /shrug
EDIT:
Tried "busybox sysctl -w vm.dirty_ratio=10" and didn't see a difference. Then I set it to 5 and rebooted and swapd0 hasn't gotten higher than like 5%. I still see it somewhat often but never too high. Maybe setting it to 10 would keep it from coming up so often but so far I'm happy :-D
Re-EDIT:
Took a few hours but eventually want back to constantly seeing kswapd0 again. I flashed a few rom and only my most needed apps and of course a theme and haven't seen it all day. Was worried it might be my theme (crysis revolution is worth the hassle it's amazing) but seems I got a rogue app somewhere. Gonna slowly install more apps every day and see if it comes up again.
Later....
Anyone else using QuickDesk? That's what was doing it for me. Installed it and kswap started acting up. Removed it and haven't gotten a single alert about it all day.
Hi guys,
I'm struggling with this problem too. I had it on Froyo 2.2, with Z4Mod or OCLF V2.2. Then I upgraded to 2.3.4 and flashed speedmod k15h.
The damned kswapd0 process still acts up, but I think I figured out the cause(don't have a fix yet, maybe someone who knows linux better can help us).
kswapd0 acts by transferring data from RAM to the SD Card when there's low memory. For example on my I9000, it starts doing that when things go under 10-8 mB of free RAM(Actual RAM, please install Galaxy Tuner and go to Memory Management to see the real figures divided by MemFree/Buffers/Cached).
For example, I had ~6500kb MemFree, then the CPU got to 100%; of course, kswapd0 worked it's "magic", and when it finished the MemFree got to ~26.000 kB.
Also, kswapd0 ceases to use the CPU if you Flush File Cache. So this is a memory handling problem.
I'll try to find a setting inside Galaxy Tuner to see if this solves the problem.
BTW, could Saiboogu, or anyone who had this problem give us the memory handling parameters they have now on their ROMs? We would need the File Cache control settings(SWP/VCP/DEC/DWC/DRA/DBR), and the Application Cache settings too(FA/VA/SS/HA/CP/EA). Maybe this will fix it, because I have no other explanation(and hope) right now.
Don't be afraid to chip in your oppinions, let's find a solution to this sucker(literally).
Are your Rooted? Probably so if you have OCLF installed. My bad. Ok download any terminal from the market and run these commands:
SU (hit enter and a SU permission will pop up-hit yes)
The $ will change to a #, then type
Busybox df -h (with a space between x and d and F and -)
I'd like to know that the read out says.
If it says what I think it will, then I might have a cause of the issue. Maybe not a solution but I am pretty sure I know what it is.
Who, me? I don't have OCLF, I'm running Gingerbread 2.3.4 XXJVQ + Speedmod Kernel.
Do you still want me to run the terminal command and let you know the response?
Yes you and sorry about that. I missed the "HAD" part of the sentence. The point really is are you rooted and can you please run the terminal commands and post them?

Code:
Busybox: not found
What the heck?! It's installed. 1.19.3.
Use your file explorer and go here /system/xbin and tell me if busybox is in there?
Yes, 233 files in the xbin folder.
Also, if I go into BusyBox, it says: Installed version 1.19.3.
And if I click install it says: BusyBox found (/system/xbin).
L.E. I reinstalled Busybox and it works, give me a sec to post it here.
L.L.E. - Here it is:
Ok then try it again
Open terminal and pull up your keyboard.
Type SU [enter]
then type busybox df -h [enter]
This will show how every piece of your phone is partitioned. kswapd0 is nothing more than a Swap file. Think of it as a holding zone for apps that you have running. Like this. You are in the XDA app and looking at things. Then you come across a file that has a link on it. You click on the link and it pulls up an address in your Browser. While the Browser is running, the XDA app is kicked to a SWAP partition so that it doesn't have to be restarted when you click out of the Browser, just "reinitiated" so to say.
Some ROMs/Kernels use SWAP, although most don't b/c Andorid does a pretty good job of task managment on its own. In the old days before you had 2.2, you could not move apps to your SD card without partitioning your SD card and using some ADB scripts to force install them on your SD-EXT partition. Your, say 8gb, SD card would look like this FAT 7gb, SD-ext600mb/ swap120mb. What would happen is that your apps would download from the market right into you SD-Ext partition and you would have nearly full internal memory b/c well nothing but /cache was taking space. Swap would help the app launching process and also task management.
So you say, why the heck is he telling me all this for? Because you have a rogue app that is going into your swap partition and not coming out. It is running in there all the time. Swap is for short bursts and when you back out of say the Browser from above, it would close and your XDA app would come out of Swap and back into "active".
Find the Rogue App and you'll fix your problem.
Edit:::Ok so while I was typing that you posted your screen shot. Same from above applies. You have a rogue app that isn't shutting down. Need to find it.
Sidenote::Your /system is almost totally full. You might be needing to get rid of some bloat here pretty soon or you will find that you won't be able to install some apps from the market. Plus I bet some of that bloat is running in the background eating up RAM and battery. You'll have to search for what is and isn't safe to remove.
So that means the Minecraft Demo and SVOX Language Pack are the rogue apps?(looking at my screenshot).
Will uninstall and Reinstall fix the problem? I don't really care about Minecraft, but I paid for Grace... Well, for her voice to be more precise.
Try using Titanium Backup Pro and "freeze" them before you uninstall. Bet those are the problems. Last time you played Minecraft, did you exit out of it? Bet it is still running in the back ground. Try the freeze and then see how yout CPU is working with one frozen or both.
Good luck and hit that thanks button. Kirk out!!
I uninstalled Minecraft(It doesn't show up in SU anymore). The thing is that I didn't even start it after the last reboot, so I have no clue how it got there.
I'll see if things shape up without uninstalling SVOX, then if not, I'll freeze it.
If this fixes it, you'll not only have thanks from me, but from all over the world!
Thanks! I'll let you know of the progress!
I uninstalled both apps, the SU report is "clean". Kswapd0 still shows up randomly eating CPU.
Can't we just turn off swap? Something like this: http://androidcommunity.com/forums/f4/how-do-i-disable-swap-34955/
Code:
su swapoff /dev/block/mmcblk0p3
I'm running stock 2.1 with JIT v2 enabled and SetCPU, but i've noticed an increase in Lag lately.
Is there a minimum of free space recommended for Android to run better? I've checked a few similar threads across xda and others but i couldn't find much useful information. My main memory currently has 100 MB and the sdcard 1,14 GB of free space.
Or maybe it's a cache issue? Never cleaned cache files before, can they actually cause lag? Hopefully is not the first signs of an incoming hardware fault.
Try using CacheMate and see...

Laggy after JIT enabled?
Normaly,the phone will just lag for the first 30s-1 min after the booting.
After that,the phone would work like a charm.
Also,remember to maintain enough ram for you phone,kill unneccessery apps.
Also,check you SetCPU settings,I used the performance and set to highest frequency(not to worried the battery,my phone usually drops 2-3% for one light)
If problem continues,just reflash and problem should be solved.
cheers,

I have no idea what happened, phone was very slow for the last couple of days, but out of nowhere it simply got back to it's normal behaviour.
Since JIT my x10 has been working very smoothly, hence my surprise when things started stuttering like crazy, the only thing that made it lag like that was a beta for Fennec/Firefox i've tested, but that app was already uninstalled when the problem started.
My noob knowledge of the Android OS led to a conclusion that some app in the background was misbehaving and the system itself shut it down eventually. Does it make sense? Watchdog's last alert accused Pulse News, but nothing looked out of the ordinary.
It started again yesterday, this time i've got random boots as well. Uninstalled a bunch of apps and the difference in performance was instantly noticeable. I've removed Beautiful Widgets and Lookout, but the former is more likely to be the naughty app.
too bad i've payed for that crap.
I've been running Overcome 2.3.1 for awhile now and I'm interested in possibly overclocking and/or using the V6 memory hack but I have reservations. I'm wondering what you guys are using that's stable to accomplish speeding up your tabs. I read about certain problems with Flash while using Pershoot's kernel and I haven't really found any substantial info on overclocking. I own SetCPU and have done it before but not sure what kernels support it on the 10.1. Fired it up on my Tab and it kept crashing and while changing the governor worked not much else was.
I'm not against changing ROMs to accomplish this but I'm not interested in buggy crap aka non-working camera/gps/usb charging.
Any suggestions or links would be appreciated.
update- installing pershoot's last hc kernel and then I'm going to try v6 - - any advice on what hacks boost performance the most besides OCing?
V6 isn't a hack. Its a script that modifys memory settings to increase settings. However, just run through the initial startup of V6 and it should automatically calculate the settings your tablet needs. Once that is done, you should also install the nitro lag nullifer (option 11 possibly) from the V6 script.
Also, task's v14 ROM is very stable and has few or no bugs and includes pershoots kernel. My wife uses it and she doesn't have any problems.

Thanks for the suggestions. I'll take a look at Task. V6 is next on my list.
**update** I see that V6 is in Task so extra thanks. Trying Task Full now.
I'm running Pershoot's latest hc kernel (january) and so far it's nice. Only issue is when forcing OC to 1400 all the time. If I do that the system's camera won't load at all. 3rd party cameras work fine though.
Can't believe how fast and stable it is at 1400. Any lag I had before is gone. I was beginning to think many apps had memory leaks since I still had occasional lags using Overcome but OCing has made that disappear. Kinda shocked battery life isn't impacted at all either. Samsung really dropped the ball with the software on this tablet.
Not seeing the bump in HD mkv video decoding using BSPlayer that I expected.
Just a heads up- hack means modify, among other things. For some it implies some type of negative action but many people don't view it that way anymore.
No problem. And when I think hack, I usually think about something that isn't executed very cleanly and half-ass work-arounds are necessary for it to work (e.g. hack-job)
Sent from my MB860 using xda premium
Yeah like the ROM Samsung released for our tabs. Then there's the half-assed professional meaning. Example - Those hack devs at Samsung.
So far I'm liking Task 14. Spent most of my time trying to defeat the media scanner bug. Tomorrow I'm gonna get on V6 unless the script is already operating.
