Alright guys, lets hear the opinions of end users so that people can decide whether z4mod is better or voodoo 5 for froyo.
Basically both convert the /data to ext4 (also ext2 option in case of z4mod) without loopback etc. i.e. direct conversion from RFS.
Pros of Voodoo: Proven fast lagfix option for Eclair.
Pros for z4mod: can be patched on any kernal
Now, anyone who has used one or both on froyo, can you all share your personal use experience for these lag fix options ? I am not talking abt quadrant scores since its the practical use that matters afterall. No point in waiting for gallery to load pics when the quadrant score is 1900+ !!
I am still using voodoo on JM8 and after about 200 apps, its still not lagging. (well except for some scroll lists stutter there is no lag whatsoever). However, I am also using autokiller with agressive settings, which is also playing a big role in keeping the lag off.
Aim of the thread is to help new users decide which version of lagfix they want on their phones based on their preferences and user opinions !
I really thought that z4mod was also going to convert different partitions but I haven't looked into it yet so i can't say for sure. If it does convert the other internal partitions that might make our phone even more responsive...
Edit: Yeah, converting all partitions is the intention but for now it only converts the /data partition.
Should provide more or less equivalent results...
Have used both and both provide more or less same result. I am slightly more inclined towards z4mod as that allows you to patch many kernels without having to rely on the devs to do it for you (I know Supercurio is working on a similar approach as well). So it is a much more DIY kind of solution.
You should include rfs free rom from sztupy, OCLF from RyanZa, and apptonand.
In my experience, I am currently running voodoo pre3 and it is fine but need more days to see.
OCLF was not really a fix on my phone.
RFS free rom is awesome (v0.1 was faster than 0.2) but battery is discharging really too fast.
APP2NAND was good with app but not very useful since you cant add a lot of app to the nand.
So I would say:
RFS free rom is the best lagfix but battery drain make it hard to use.
Voodoo is very good.
App2Nand is good with app on the nand but thats all
OCLF doesnt really fix lag on froyo (was good on eclair).
I recommend using voodoo while waiting for RFS free rom to be updated.
note: I will try voodoo with app2nand later and see if it can be faster.
I didn't try z4ziggy kernel mod yet (need time to try lag fix, at least a week with each...)
Voodoo was awesome on Eclair, but once the z4mod came out in Alpha - I got curious.
And I'm glad I decided to try it. It creates an extremely smooth experience on the SGS. From what I've been reading about the newest release of Voodoo, some people are having slight lag when opening the app drawer when using LauncherPro on Froyo.
I can't give feedback for both of them on Froyo, but I'm satisfied with z4.
Coke or Pepsi?
On the lagfix part, if using Ext4, Voodoo and z4mod for Froyo are the same.
Voodoo use optimized mount options for Ext4 in 2.6.32 z4ziggy don't do yet but will.
The rest (conversion process) is cosmetics.
You know, it's just an Ext4 filesystem
Froyo Voodoo is not yet available with stock kernels but all the code is already here, it will appear very soon for every Galaxy S phone (not just I9000)
Source came first because it allow to be creative, not just "fix things".
Some more memory management optimizations and filesystem parameters may be improved @Voodoo in the future, but I'm sure they will also be in z4mod (and the other way of course!)
z4ziggy is on #project-voodoo since the beginning and we share our infos and experiences
project-voodoo aims at also improving eye and ears experience with Voodoo color and sound.
The lagfix part is pretty much done since months
I am using z4Mod too. I'm using it now for 3 days and I can't complain about it, everything works fine. There is no lag, no problems with root... Can't wait for the next update
Can't say anything about Voodoo, because I didn't try it.
I actually had both (z4mod installed yesterday, and voodoo today, both on a fresh jpm), I would say they are probably on par but I thought voodoo setup is more seamless than z4mod.
I tried voodoo5 pre3 and except for 1/2 sec booting color scrambled screen is perfect with jpm root. Don't know about z4mod
RFS Free Rom from sztypy is still very experimental and not ready for general consumption. That is why i didn't add it.
As far as OCLF is concerned, its not actual conversion of file system so its in a different category (that is why it works on most builds - eclair or froyo) since it uses a loopback system .... gets laggy over time and with lots of applications installed + space issue.
More compatible and feasible options at this time are only z4mod and voodoo. I agree with supercurio regarding the ease of installation of voodoo and comparatively less complicated setup process. About the bugs, i am sure they will be sorted out in no time for both voodoo and z4mod.
Also ... as supercurio said, another benefit of voodoo is color and probably sound fix soon ! which is better for a full experiance. (maybe he can develop a real firmware someday which samsung ment to do for galaxy s in real )
But the question is between lagfix options. Both only convert /data partition and not other partitions at this time. Also, has anyone tried z4mod with ext2 conversion ? does it actually give better speed or is it just an assumption. Real use testing is the one which matters afterall !
If ext4 conversion is same in both voodoo and z4mod, then why there is a difference in quadrant ? just curious not that i believe in quadrant scores as the tests are very primitive and does not depict real usage at all ! so which one is actually faster ? can we actually perform a read write speed test ?
JPM/JP6 "GoodBye RFS" ROM 0.2 vs voodoo pre3 -> voodoo pre3 [GRFS, its good by still need some fixes]
Interesting thread. Hope we can get some nice conclusions and the thread don't get contaminated by wars between devs or fanboys
-I didn't try the voodoo5 pre3 yet. After reading the feedback of some users I think I'll wait till the next beta (pre4?).
-I'd like to test z4mod but the install instructions seems bit complicated to me so still didn't tried...
So I just can recommend sztupy rom, its still at experimental stage but exceptsome problems I'm having (random vibrations) it seems stable.

I agree with most of this post super with the exception of lag fix being complete. Until the /dbdata folder and others can be converted on voodoo, lag is still present on the apps that use the database folder. Like google voice, sms, touchdown contacts. When you have a lot of emails or contacts or sms, lag can be upward in the range of 5 seconds before those apps open.
The voodoo fix is great, but not complete. Think how much smoother this phone would run with the rest of the folders converted to a file system other than rfs.
Super, your work is awesome thanks for everything!

I'm using the voodoo lagfix on JPM, and it's really much faster and smooth than the OCLF lagfix.
don't know for z4mod... :S !
I used OCLF before voodoo was out and after 4 days it feels a lot slower
Voodoo is a brand I have always trusted and it has not failed.
I've been using Z4mod with the EXT2 filesystem for a few days and I'm very happy with it. Seems very reliable and performance is fantastic.
I haven't tried Voodoo myself. But I don't think the two will be very different. Although Voodoo includes changed screen settings like colour and sharpness which some people will like, depends on personal taste.
I've tried OCLF on JPK and now Voodoo on JPM.
So I don't know if they can really be compared.
But as others mentioned, OCLF on Eclair was blazing fast, on Froyo I didn't really feel a difference.
That's why I stuck to Doc's SuperSlim ROM with my second JPK flash.
Yesterday I applied Voodoo to Tayatuma's SuperLite and it did add additional speed.
Default browser is laggy but that's a different problem.
Would like to try z4 in the future, but very happy with Voodoo atm.
I have around 30 apps installed.

At now there are a lot of solutions for fix the lag issue on Galaxy S series... and some of these are based on ext4, jfs, ext2 and other. My question is: wich is the better filesystem for the hardware of the Galaxy S? I think than any solutions have pro and cons, so which is better for life battery? for speed? for CPU usage (that maybe is the same of battery usage)? for smoothness? And for other aspect that I have forgotten or omitted?
As a matter of fact, you won't notice any difference between filesystems' speedboost, especially, using Froyo. I tried several ones, but using RyanZA's OCLF 2.0: it delivers the easiest decent way to boost your GT-I9000 in my opinion.
No idea but some say ext4 is overkill and wastes cpu time. Ext2 would be way to go , I myself use jfs
Sent from my GT-I9000 using Tapatalk
I wouldn't recommended jfs. My experience with it has been far from great, it's unstable and has bugs.
I'd suggest ext4 but it appears to use more battery then rfs. As far as ext2 goes, it seems the most stable and less consuming but it's not the fastest imo.
Well battery life is the price to pay if you want something faster, EXT4 is the way to go.
And pinned topic that in detail describes differences is just invisible?
JFS has some bugs, Timezone and Locale changes every reboot
I think EXT4 is the best choice in terms of performance, but not for battery life.
yep
EXT4 is fast and best for galaxy s
You can't say that jfs has timezone bugs and so on, as there are users who don't experience this, like me. For me, jfs is the best fs, and I' ve tried them all.
But I guess you should try then all. It's a matter of opinion and taste, like opera/chrome/firefox

This is a discussion only about the better filesystem for the Galaxy S, not about the better LagFix. So I don't see the point of your contestation.
Sent from my GT-I9000 using XDA App
JFS is the best in both battery and performance but it has a nasty timezone bug (locked to 00:00 and it resets on every reboot)
EXT4 is very fast and most stable and you shouldn't feel speed differences when using JPA or JPO.
EXT2 may cause data loss.
But EXT4 for what I have seen drain battery a bit faster than EXT2 or RFS...
Yup, me too but it's still the best compromise until somebody figures out the JFS bug...
ext4 is the best all-round. I'm on JFS at the moment and it seems unstable.
Why unstable? (besides the timezone issue)
Random stuff happening I didn't get with ext4 like hangs, phone resets, takes ages to wake up from lock etc.
FWIW, I've had little to no problems with EXT4 as a replacement for RFS.
Haven't compared with JFS in terms of battery, but I do get pretty good life overall, and very much similar to RFS.
IMO ext4 is the best at the moment. Smooth, fast, stable, reliable. But the minus thing is, it uses more battery.

You must have done something wrong, I had none of those...
I have encountered some trouble with the latest darky's en Doc's romkitchen roms/kernels when it comes to 3D gaming. Some high end games run smoother on stock froyo then on rom's that are supposed to be smoother. An example is n64 emulator that just came out (Can highly recommend it, buy this thing!)
An other example is dungeon defenders first wave, which runs awesome on stock but has some hickups on Darky 9.3/9.2. Quadrant however seems to be better on custom roms en Kernels.
blah blah blah, MY QUESTION:
Which Rom/Kernal combination is best for 3d gaming?
Heard some good about Insanity? Anway lets get the discussion started!
Selfbump... Will flash all the major combination on Saturday to test n64oid, and dungeon defenders. Updates will follow.
n64oid? AWESOME!!!!!!!!!!!!!
Thank you for telling me about that! I miss n64 so much!! Especially Zelda and Bomberman!
I'm using Darky's 9.3 with DamianGTO's v1.1 Gold OC to 1.2ghz full ext2. I get 55.6 fps on most games which is perfectly smooth IMHO. I was told not to use setCPU with it though as it messes with the governor but I'm thinking it's a good idea to use just to set to performance for perfect game play, no set-on-boot settings.
Did you set up your lagfix to ext2 or ext4? They are both similar but ext2 doesn't have journaling and so it's faster in use but a little more risky if you don't have backups. Ext4 is slightly slower due to the journaling but with faster boot times and it's safer in case of a battery pull. (keep in mind, I'm using EXT2 flat, not like OCLF where it's ext2 on top of rfs)

No problem, Zelda is not running very good yet, but the devs told me they are working on it. So far Mario 64, Mariokart and Starfox are running ok on the stock froyo 2.2.1
I have rfs now because its stock, but I tried voodoo with ext4. I have nandroid backups, backuppro and even titanium installed so Ill try ext2 flat this weekend.
Thanks for the reply!
Starfox was a good game so were the other two. I'll be keeping an eye on this one and wait until it's fully ready before I buy just to make sure they can get my favorite games running well so I don't get disappointed
Yeah, RFS on this phone is horrible on any ROM. It just places so much on security that you can barely get anything done. Quite frankly, it's overkill on that front, so much so that the true power and efficiency of our phones is left unrealized. There is so much debate about ext2 vs ext4 but most people don't notice a difference anyway.
I have nandroid and titanium backup, that's enough for me. One to backup in case I screw something up or need to change CSC(been having issues with HSDPA not auto connecting) and one to restore apps and settings for when I change firmwares.
i started to play legend of zelda ocarina of time on comp because it was so buuuuggy to play on my sgs i9000 :/
edit. but still i recommend speed mod and im still comparing custom roms.
After update Zelda OoT is running pretty smooth! Starfox is running a lot better to!
Im on the newest Insanity with DamianGTO 1.1 gold Kernel and im getting around 2300-2400 quadrant without OC. Ext2 is working pretty good, made sure to backup my ****
I will try some other combinations, but for now I can say this is the best combination Ive tried when it comes to 3d Gaming and maybe even the overall experience..
Respect to the devs, and feel free to share your own experience
does the overclocking of the cpu give a major boost to 3d gaming or will there be smooth gameplay without overcloking???
Tried the 1200 mhz setting and there is definitly a boost in performance. With insanity and the overclock kernel I reached an quadrant of 2690
Im gaming without much trouble now on using the ultimate 8.0 rom with DamianGTO 1.1 gold kernel, without OC.. I got a lousy quadrant of 1100 with this combination, but im running most n64oid games without to much problems. Dungeon defenders first wave and Spectral souls are running silky smooth so apparently the quadrant score is not really representative.
Tried CM7 as wel, have to say im very impressed by the overall smoothness, but its still a bit to beta for my taste. Plus, this thread it about gaming, and some games are still incompatible with CM7. This will be the ultimate rom in 2 months though.. Mark my word.
So have the OP come to this conclusion that ultimate 8.0 rom with DamianGTO 1.1 gold kernel is the best rom and kernel for gaming?
Hey all
Longtime lurker (i think i have some very old posts in here).
I acquired a galaxy and so far im pretty satisfied. But still only so-so. My wife has the iPhone4, which is also a great phone, and what i envy most about it, is the super fluid, instant response you get while working around the UI. Scrolling, opening programs... everything is incredibly smoot. Not so much on the Galaxy.
I tried doing the lagfix and rooting it also. It helped nicely with the loading times of programs, but the UI still isnt as smooth as the iPhones. And this is something i dont get. The galaxy is one of the most powerfull handsets out there, but still cant reach the lvl of smoothness as you get on an iPhone.
I ran Quadrant after appyling root/lagfix and scored a 2200+. Thats a pretty great score. But still doesnt feel as snappy and responsive as i find it should.
Ok well, what i want to know... is there anything out there that could help improve the UI responsiveness? Another ROM? Another Kernel? Or is this something that is just inherent with Android and/or Samsung, in a way that i will never have that?
First of all, ignore Quadrant. If you rooted and did a lagfix on the stock firmware, then you likely used OCLF. Ext2 from OCLF inflates Quadrant scores due to the looping method it uses. The only real way to judge your phone's speed is out it feels to you, and if it feels sluggish then you have work to do, regardless of the Q score.
I would definitely recommend flashing a new kernel. You should start with Speedmod (http://forum.xda-developers.com/showthread.php?t=822756), just because Hardcore's instructions for flashing the first time with Odin are very clear and complete. Follow them exactly and you should be good and then you can use a program like SGS Kernel Flasher to try other options easily (just remember to undo lagfixes and tweaks in between flashes).
Personally I have used Speedmod, Super Optimized and Ultimate Kernel and they are all fast with good performance. For me the best has been Ultimate (with all Ext2 lagfix) but each person and phone are different, so play around with different choices. If you wish to go all out, you can read up here about flashing the Mod as well.
I was also quite dismayed and surprised by the performance of my Galaxy out of the box, but now with a smoking kernel and lagfix in place, it is easily as smooth as iOS.
Good luck, and enjoy.
i think the most important thing is first flash one of the new firmware 2.2.1 like JS7 then it will run already smooth, if thats not enough then you still can flash a newer kernel hardcore or voodoo kernel and lagfix it.
Thanks, lagfix?
Thanks guys.
Ok i will stop using Quadrant as a benchmark for my UI experience.
Ok, flashing a new kernel. Great with some oppinions too. What are the Go-to kernels right now? Those 3 you mentioned?
And regarding lagfix, i though lagfix was almost always a part of a customer kernel? And if not, which lagfix should i use?

I suggest starting with Speedmod just for Hardcore's great instructions. However, if you are not satisfied or wish to try other options Speedmod can just be your entry drug. Once you have flashed once, you can install Clockwork Mod recovery and SGS Kernel Flasher and really go to town. There are lots of great kernels down in the Android Development thread, I just listed the three I myself have tried. Read up on them, and try the ones that have the features you are looking for.
As for which lagfix, again that is a matter of personal preference. Some say Ext4 is safer, some say Ext2 is faster, some are jfs fans, some say even stranger things. Each kernel has a different approach, as well. Again, take solid backups with SGS Kernel Flasher or ROM Manager and try each method for yourself. Just remember, be home when the clock strikes midnight, and undo all lagfixes and tweaks before flashing each time (and remember, if you used OCLF to do your current lagfix, you need to go back into that app and undo all it's changes before flashing Speedmod, or BAD things will happen).
Let's not forget about basic things, like wiping the phone?
I was actually looking for exactly the same things, and I was changing kernels, roms, themes, etc. etc. while I realised it's not just that.
Go one step further, and what I found is that under Zeam launcher everything seems snappier(the kleine crocodile), than before.
I also disposed all theme, and extra stuff, that made the rom "heavier".
I cooked my own ROM in doc's kitchen, and indeed used hardcore's kernel with ext4 lagfix.
Not only the phone is pretty close to the iphone responsiveness, but the battery life is also great!
2200+ Quadrant scores?
I've got around 1100 on Darky's Rom 9.3 and the responsiveness is amazing!
im using newest rom from doc's kitchen with supercurios kernel.
i used zeam launcher before which didn't feel snappy, i'm now using Launcher Pro which just feels alot snappier.

forget the scores, yours with just 1100 could be faster than one with 2200 in daily use.
A friend of me has a iphone4 and I also think that the iphone4 is just smoother than the galaxy s.
I'm on darky 9.3 with voodoo lagfix (which is included in the rom) but still I have laggs on screen. My sister just bought a htc incredible S and its also very smooth but again not as smooth as the iphone4. I just personaly think that apple has made there a good job...but there is alot what I don't like at the iphone4.

I agree. I've tried many new custom roms and lagfixes, and although they help, they still don't seem to make the phone reliably and constantly smooth. I occasionally still have some UI lag or freezing. I praise 2.2.1 for making the phone feel as smooth with RFS as it does on EXT4 though, and now I usually don't bother "lagfixing" the phone
I use TouchWiz, so I think inherent bugs in the UI are at least partially to blame. I noticed using a 3rd party launcher generally felt a bit smoother than TW, even though I like the TW layout. I'm going to reformat the phone and load JS8 with Speedmod and am leaning towards using the latest GO Launcher as my default to see if there's any noticeable long term improvement in smoothness
really everyone is going lag fix lag fix hardware way? seriously the TW launcher is the problem , its NATURALLY LAGGY , imo get Laucher pro you want silky smooth get launcher pro and set it as default home sure as hell looks better and is more fluid than any other loader out there , not one NOT ONE little hiccup ever just soo silky smooth , never even a slight tiny tiny not even micro second lag , app planet > launcher pro > facebook widget > messages widget > normal background not live > 3-5 pages = win
But I like the look of the twlauncher more. Somehow I just dislike the look of the launcher pro

Hi, so after cm rooting i noticed there is also an ext4 upgrade...is this worth it and will I have data lose during the change? Im on 2.3.3 and am wondering if it is really worth it! Ed
are you kidding me?
besides that this post should not even be in this forum (try Q & A) there are hundreds of other posts and threads discussing this topic if you only use your -(0-0)- !
Yes and no
It may have some advantages but as for what I'm not sure but as for nay major advantages I would say no. I'm still using EXT2 and my benchmarkes are still 1900+. I've tried almost all the other lagfixes and found no real advantage. The only thing I hate about custom kernels with lagfix is the secondary samsung splash screens and custom splash screen. They kill the post time.
I would say it isn't as worth it as what people say. First thing most people do after converting their filesystem is run quadrant. It's possible that improved quadrant scores don't translate to real world performance though.
Even worse, running quadrant actually engages the placebo effect so you walk in with a more positive impression. Meanwhile, I don't recall ever seeing anyone from the EXT4/EXT2 i9000 community running blind tests, and neither development community has actually shown any evidence formal testing has been performed. All the arguments seem to be based around quadrant and PC testing. If methods like this were applied to clinical testing, every drug would pass
Honestly, give both a try, but do it blindly.
Why Quadrant may be wrong
This is just a bit of background why Quadrant's scores may not reflect real life performance. Until we check the actual ratio's of Quadrant, and compare with actual usage ratio's though, we can't identify how "real" it's scores are.
Consider a benchmark which produces 1 final score. It may be calculated by:
[MAX TIME - Time to read 1000mb] + [Max time - time to write 1000MB]. In this case, both scores contribute to 50% of the final score, which can be worth 2x MAX Time.
Scenario 1: Time to read/write is both the same
Scenario 2: Read time is 1% shorter than Scenario 1, but write time is 1% longer. Both will have the same score in Quadrant..
Scenario 3: Read time is 5% longer than Scenario 1, but write time is 50% shorter. Scenario 3 will get the best score
Which one is ACTUALLY faster though. The benchmark-toting individuals will claim Scenario 3 is faster, because of the score. HOWEVER, that may be incorrect. Consider the following:
If a user reads 100x more data than they write:
1) Clearly, faster read scores are more important.
2) The BEST filesystem will be Scenario 2, despite being equal last.
3) Scenario 1 will be mid place
4) The scenario with the best score, will actually have the WORST performance.
5) A drop in 1% read performance would need a HUGE increase in write performance to actually be faster.
Until we have an idea of how accurate Quadrant REALLY is, run your own tests, and do so without knowing which filesystem is running. High quadrant scores may boost your e-penis size, but as you can see, it is theoretically possible for the scores which are produced to score slower performing filesystems more highly than faster ones. Disappointingly though, a decreasing number of users/developers at XDA these days are actually interested in the truth, and simply in not being wrong.
Even worse, the community for some reason seems VERY anti-RFS, and wont give it a chance regardless. It might be a LOT better than it used to be. Either way, it seems to be good enough for me.
Ignore the theatrics and run a blind test. That's the only way to determine what is ACTUALLY faster.

I guess you mean CF root right? Will just answer the data loose question. No you shouldnt. But do a backup before. Its fast and easy (if you are on CF root that is)
If its worth depends on you? You experience any lag on rfs? Phone slow?

What samsung splash screens and custom splash? What rom and kernel are you on? And what lagfixes? And we both know quadrant score doesnt matter does it ?
Yes, it's worth it. Some things (Android Market, Gmail) works really MUCH faster then on rfs.

Hrm, I've never noticed a difference. Market is slow on any room, hell market.android.com is slow too. Gmail always worked fast for me, on any rom.
Personally, I don't see or feel the point in using anything but rfs, but I suppose if someone has half a bazillion apps installed, then maybe an alternative filesystem might be better.
I say try it. If you notice a difference, good for you. If you don't, then stick with rfs.
What about battery performance ? from what I have read, battery performance is also better with RFS.
I always use ex4, its not as needed now on gingerbread but I just prefer the file system...it is better than RFS...but RFS has improved a great deal so you may not noticed that much difference, the rom may become a little smoother..You wont get data lose because of ex4, maybe the way the kernel is built...dont forget that 2.3.3 gingerbread is still beta and without the source code for the kernel you cant expect great things yet, although chainfire has done some amazing work and now we can change the file system using his app....works really well.
Also regarding battery, the difference in performance is such a small margin that its not even an issue.
What alot of people aren't aware of is that the Nexus S for example uses ex4 file system as default straight out of the box
Its not just a lagfix for the galaxy s, its a very good file system too...
Just a side note on Quadrant, ex4, ex2 will trick the app...if you buy the pro version, you will see how much the file system stretches on the bar...Quadrant is more for fun....or HTC
Think it´s worth cause rfs slow down your system after a while
This could be a noob question but I haven't found an answer yet. Exactly what performance increase will I notice when enabling a lagfix?
I have tried so many ROMs and tried to compare them in terms of battery and performance with lagfix on and off but I don't notice any difference.
Does the lagfix help with general snappyness or load times on apps?
Thanks.

Lagfix refers to fixing the lag of the stock Samsung "rfs" filesystem by converting it to an "ext4" or voodoo filesystem. It overall speeds up the responsiveness of the phone when pulling something up or scanning partitions etc. It does in fact increase performance.

This is true upto froyo roms. I feel as though in gingerbread, rfs is as good as, if not better than, ext4 (lagfix).

I definately have noticed this as well and totally agree.
