Z4mod over in I9000 converts data to ext2/3/4

My goal in posting this was to get a vibrant dev on it, and ttabbal has taken on the task. Thanks to him. His thread is http://forum.xda-developers.com/showthread.php?t=822964 this thread can be closed.

This looks very promising, curious to see how that shakes out on the US variants...

Isn't that what voodoo does?

Voodoo requires a special kernel, but what if you wanted stock kernel and ext 4? Thats where this comes in I think.

This looks like a major step in the right direction. I Can't wait to see support for the Vibrant so we can rid ourselves of rfs. Whew!

This also looks like it requires a kernel, and EXT4 is the clear choice, so its the same as Voodoo to me.

But you would still have to mod the stock kernel to allow for this? I don't think the stock kernel supports ext4 right?
Either way, this is pretty awesome =)

Agreed.... But I am ok with new ideas. Might find something useful that can be married into voodoo. Too bad I have the larger NAND chip, so I am still w/o voodoo. :/

I would agree, but voodoo doesn't have the /system and /dbdata which would speed up other apps for me. For example touchdown connected to exchange still has a bunch of lag but everything else flys.
I believe if all is converted then the whole phone and all apps and task would be much zippier. I may be wrong though, when I used ryanza ext 2 mod touchdown would load instantly. Voodoo takes at least 5 seconds.

The thing is, Ziggy is looking at a total RFS replacement vs supercurio's /data rfs replacement. So the entire phone would run much better and more efficiently.

Exactly my point. All the file system is converted instead of just /data = better than voodoo IMO.

supercurio hasn't tweeted anything about a release for beta 5. So...I might take whatever master says with a grain of salt. Oh...look at the time of the last edit - 10/13.

I'm considering building a kernel with the init.rc and other changes needed for this mid. Probably look into it next week.

I have a large NAND vibrant and have been waiting for voodoo beta 5. Tried this last night with the JI6 kernel. It worked! I'm using ext2 right now. I haven't tried going back to RFS yet. I hope to try that today. If it works and time allows I'm going to try a Jac kernel and ext4.
This is only converting /data right now but the user experience is excellent. I haven't noticed any lag at all and there are no space limitations like with the loop back setup.
Sent from my SGH-T959 using XDA App

Keep us updated fastkatt, I too have the larger NAND chips and have been dying for a decent lag fix. I know there is a voodoo workaround, but noone can explain exactly what it does. I would prefer something that accounts for the extra space and makes use of it.

Can anyone tell me how to determine the size of the NAND in my Vibrant? I have seached this but have not found the answer....
Thnaks..

Help me out with my captivate

I just installed voodoo and then used oclf, but now my accelerometer is all jacked up, anyone else have this problem or know a way to fix it?

Stupid question but why would you put oclf over voodoo
Captivate
Cog 2.2

I saw it on a forum, and after I did it it went from a quadrant score of 1600 to 2300, so it works but the only thing that doesn't work is my accelerometer

What Rom are you on? The only suggestion I can make is to remove one of the Lagfix. Or flash back stock. I would search the thread or even just Google your problem. Someone may of had the same issue and found a way to fix
Captivate
Cog 2.2

You're kidding, right? Please tell me you're a troll and you didn't really put OCLF on top of voodoo.

Don't put OCLF on top of anything.
If you're interested in something faster than voodoo, check out SetiroN's kernel and/or the ROM's that use it. Such as in my sig.

What's the quadrant score on that?
Sent from my SAMSUNG-SGH-I897 using XDA App

Quadrant score has nothing to do with how it performs.

The last two lagfix options in SetitoN's (or stutzy's) kernel are basically the same thing as oclf over top of voodoo - though the on only thing that would be good for is quadrant scores, won't really notice much of a real world performance dif. And that kind of lagfix combo is really going to cut into your available space on your data partition.

Then what would you recommend performance wise
Sent from my SAMSUNG-SGH-I897 using XDA App

Honestly you sound like a noob and SetiroN's kernel requires a certain skill level to install / debug because it is still in alpha stages.
Just stick with Cognition if you want my advice. It is plenty fast, has a great battery life, and automatically works with Voodoo. And it is fairly stable. OCLF on top of it will not help.
In my experience SetiroN's kernel has better performance but takes a cut in the battery life and also has some wierd bugs.. you don't have full functionality in every way... lots of people like it... but if you want my recommendation it's going to be a lot of work for you so go with Cog instead. if you go with setiroN expect to put in a number of hours learning how to get it working.. and expect a few people on that thread (not setiroN) to flame you if you post a question about hwo to get it working. last night there was a lot of drama. larger point is you will probably get criticized there from a few bad apples.

I am a noob, but I can figure stuff out, I'll give it a try. Thanks.

I am currently running Cog rom SetiroN's kernel with jfs advanced all jfs lagfix and I am happy with my phone's performance.
Don't know if this is the best performance or not as that is somewhat subjective as to what will rework best for every one on their own phone with their own configuration.
My recommendation is run what you want to run on your phone. If quad scores are important oclf type lagfix's that make some type of buffer that sets on top the data partition will always outperform in the quad's input/out bench mark and get overall better quad scores, but the buffer wil take up valuable space on your data partition.
The only way you can know for sure what works best for you is to try them out, do some actual time trials and stress tests with the apps you use and pick which one you like best.
What ever lagfix you choose make sure you know how to properly disable it when needed before you actually install that lagfix.

Ok cool, I really like cog ill try putting SetrioN kernel on it, thanks man

Just my 2 cents but make sure you read up and understand Setroin before you flash it

Yup just did, I gave cog with SetrioN
Kernel, its working out great so far, thanks a lot.

Lagfix question

This may be a completely stupid question but I've been flashing roms for a while now... Tried pretty much every rom for the captivate and I noticed that lagfix makes my phone lag.. The only thing "better" seems to be quadrant scores.. Is that normal? Am I missing something? Lol any input would be great.. Thanks
Sent from my GT-I9000 using XDA App

Oh I am currently using apex 7.2 .. And I disabled lagfix .. Is it ok if I disabled both settings in cwm? Just want the best possible settings.. Thanks
Sent from my GT-I9000 using XDA App

Don't worry about quadrant and linpack scores. Just focus on your experience on the rfs and ext4. Which one do you think is better? Personally I use rfs because some people say it saves battery, and it does not get corrupt as easily as ext4. But really its your ppreference.

[Q] Hit the 5 month mark, should I finally root and lagfix?

I have noticed that when I click a button, I usually have to wait from 1-2 seconds before I get a response. Would lagfix take care of this? I'm running stock Froyo.

As many have stated all the lagfix does is help fix the very slow rts file system, it most likely would not help in your case.
Best thing to do is delete unused apps, and reboot the phone every day or to(seems to help mine out, cant guarantee results)
Also if you havent needed root in 5 months you probably don't need it

Unless you want to use opitimised roms, I dont see why you would need to root. Check your memory usage delete unused apps and reboot the phone ever once in a while.

My honest opinion, no reason to have an android phone if you are not using roms

Gonna have to agree with mcord here. had to go back to stock froyo for about 5 hours (didnt have all my tool to get back my 2.3.4 ROM) and it was horrible.
you might not be up for it but i really recommend flashing a Froyo Custom ROM from one of the xda DEVs. you'll love your phone and be amazed that it can be so much smoother and responsive.

First thing I did after i rooted was flashed a new kernel to overclock. Performance increased but battery life was poor. Then my first rom was cm7..been hooked since..tried miui once then went back to cm7.

No a Benchmark score is not the best example to lag fix your phone ,but the more power you get, plus better battery life and, better perrformance are great reasons to lag fix your phone. I just posted the quadrant score so kb0npw can see the increase performance from normal rfs file system to ext4(lag fix).

I dont think he thought it meant everything, he was giving a simple before and after which showed some improvement. Quadrant can actually be pretty useful when trying to gauge what effects certain changes have on your phone, say you score a 1900 before you change 'x' and then 2200 after that change, then you know its increased performance somewhat and youre moving in the right direction. How much it has increased your performance is debatable, however. My point is quadrant can be a useful tool when making changes on your phone if you take it with a grain of salt.
EDIT: To answer op's question, Read up on some custom roms and flash one, the difference is phenomenal and you'll wonder how you went 5 months without them. If you have any other questions feel free to pm me and I'll see what help I can be

CyanogenMod or Overcome?

In your opinion, which is better, CyanogenMod or Overcome? Currently, I'm running Overcome 2.0, but have often noticed lag when I'm using it, though I'm not sure if this is a problem with the ROM.

Overcome 3.10 it looks good and is fast. I prefer touchwiz to cyanogenmod because of task manager and other samsung apps.
If you want speed go for cyanogenmod, if you want more functionality go for overcome.

No, because cyanogenmod has all bloatware removed so it is faster.
Sent from my GT-P1000 using XDA App

cm7 is fast but missing optimize code for tab , your music player drain 3time more than stock kernel. most video codec need software decoder. These are stopper if you use them frequency.
but things i love in cm7 is theme , i love white notification bar which cannot find in other roms.
you also can redesign auto brightness level to work as it should to be.

I agree with you, performance are not calculated by numbers of bloatware. Quadrant checks how fast your tab performs when doing integer, float, etc calculations, and also io checks (read, write database), 2D graphics and 3D.
check out my post about this.
if you look for speed, true open source softwares, get cm7
If you look for a balance between battery life and performance and also some stock softwares, get Overcome (if ur ok with ads blocked), the flashing knowledge is a bonus as well (thanks to thepitbull with his extensive howto).
If what you need only undervolt, add koxudaxi kernel to your stock rom.

Quadrant tests kernel, hardware and software. You may have removed bloatware but touchwiz is still there right.
