I am still trying to learn more about Voodoo Lag Fix before I download the Obsidian V3 w/ Voodoo Lag Fix (Team Whiskey).
I can't seem to find the thread about it explaining in greater detail what it is different between this fix over the other one (OCLF)
Yes, I know they are two different lag fixes, but would like to know more about the Voodoo Lag Fix in greater detail.
- I know that OCLF uses ext 2 and Voodoo uses ext 4
- I know that IT IS A MUST to disable Voodoo BEFORE flashing other ROM's
- I learned that in some people's opinion Voodoo is better than OCLF, vice versa
(These are the basic things that I know so far.)
Guess what I am trying to ask is what are the pros and cons of the Voodoo Lag Fix. (Everything explained in greater detail would be great.. just can't seem to find the thread or sticky on this topic.) Sorry if it seems that I haven't searched hard enough; I'm just sick of reading about which is better than the other ones.
Bump... are there none?
OCLF creates like a buffer between the normal filesystem and the OS. So the phone still uses RFS (the crappy Samsung filesystem), but through the buffer of ext2.
Voodoo actually converts the filesystem from RFS to ext4, and does not have a buffer of any kind.
OCLF may get better Quadrant scores, but Voodoo (or even better, z4mod) are much better for real-world usage.
so how would I go about disabling it if I ever have to reflash the phone? also, would the voodoo lagfix be better for battery life or no?
I don't really think either one affects battery life much. I get great battery life with on my phone that has Voodoo.
And to disable Voodoo, you just put a file called Disable Lagfix on in the Voodoo folder on your phone and reboot. Rebooting when enabling or disabling Voodoo can take a while, since it has to convert the filesystem back and forth.
Try browsing around the Project Voodoo site for more info.
alright I will take a look at the read! Thanks for the help!!

Voodoo would be the better fix since it uses ext 4. OCLF uses ext 2 which in the long run could cause data corruption. I use oclf because I've got the larger nand and voodoo will only install on phones with the smaller one.

Pretty much as stated above. However in the interest of quelling yet another "I'm dense and borked my phone because I used Voodoo without understanding it fully" thread please be sure that you FULLY UNDERSTAND the responsibility you have as a user of Voodoo that you read carefully and always, always, always disable it before flashing anything.
Other than that, go for the Voodoo, if you want a workable lagfix with little input from the user, go with OCLF.
Personally I had horrible experiences with OCLF on my phone and the girlfriend. When removing OCLF, it doesn't sometime remove correctly. Which left me in a huge pile of infinite force closes in a loop. Voodoo is the right way to go if you have the smaller NAND chip.
They are both about equal. In my experience, ext2 is slightly faster than ext4, but it's barely noticeable. Anyway, if the z4 mod ever gets easier to use, that will definitely be the fix to use (and it lets you decide between ext2, 3 or 4)

Oclf is a bit faster since it doesn't maintain a journal table. On the other hand, because of the journal filesystem on ext3 and ext4 your data is safer from corruption. Both tend to improve overall feel accessing the data, so it is personal preference.

I was browsing some other site when I noticed some members mentioning how android 2.2.1 on their galaxy s devices made a HUGE improvement in overall speed, basically making it stock lag free. They had the original i9000 galaxy.
The story was, when google released android 2.2, their main goal was efficiency and speed overall but mainly for the snapdragon processor devices especially since their own device(nexus 1) + many others at the time, evo, incredible, etc. were snapdragon powered. Thus, people noticed the increase in speeds and also their benchmarks increased dramatically as well. The downside was, those optimizations kind of slowed down our hummingbird devices in some ways resulting in the lag we know of. Thats why some people feel(including myself) stock 2.1 was pretty slick in basic functions.
But since the 2.2.1 was leaked, people installed them on the international galaxy s devices, and even some ports were made for the samsung Captivate. All of those devices with the updates are much faster. I tried to find people having 2.2.1 on the Vibrant, but no know has so thus far. So does anyone know of any developments on 2.2.1 for or vibrants, or atleast somehow we can try to have it ported. I mean if they got it working from the i9000 to captivate, im sure vibrant should not be that much more different..
Just install voodoo lag fix. Will speed up your vibrant and be mostly lag free. Why wait for all that. I'm using odex uvjl4 froyo stock rom with voodoo. Runs awesome.

Because whichever way you look at the RFS, it is still FAT based filesystem, inefficient and ancient, Voodoo converts that to a proper linux based filesystem that should've been on the phone from the get go.
Voodoo lag fix is the ultimate solution to the lag problem. 2.2.1. in combination with voodoo would make our devices that much better with increased cpu and file system performance over 2.2.
2.2.1 was ported to the Vibrant already. Heathen got everything working and it was amazing EXCEPT for a major bug. The phone would restart every time it picked up too much network strength signal (service bars). They tried fixing it for weeks but ultimately no one was able to fix this bug which is hiding somewhere in the radio of the Vibrant apparently. Ultimately 2.2.1 was dropped and development for it is now halted.
I believe there is some development for 2.3 (Gingerbread) from both TW, CM, and maybe Heathen as well but it appears it is still a bit too early to have daily-driver ROMs.
I hope this explains the situation.
Voodoo brought my vibrant a 1000 points higher on quadrant benchmark, everything is so much better, stop being a little biznatch xriderx66

The OP is asking for like updates that improve speed and everyone goes VOODOOO!
I understand, I use voodoo too, and to the other guy explaining to me about RFS, I know that already lol.
Thanks for the advice, but actually i already have voodoo running. Its just that I was interested in finding a more stable option, especially something that did not require having an additonal install. BTW how come people are getting such great benchmark numbers with their voodoo vibrants. I was getting close to 1400 and just did a complete wipe and reinstall and now im getting about about 1000. Regardless of the numbers, the phone seems to be flying though, regardless of the bogus numbers..

make sure your /system, /data, /dbdata and /cache are ext4, you can check with adb shell or terminal emulator app via "mount" command.

any chance of a build from heathean to test on mt dart?
Didn't see this posted here, thought I would share it. This lag fix supposedly has excellent performance and comes in APK form, so you can install it. It is compatible with Fascinate. I have yet to test it and see how performance compares over doing just a Voodoo kernel with ext4 partitions.

I have used it previous to flashing a voodoo kernel and I honestly think it just inflates quadrant scores. I notice no drop in performance on voodoo. It is however a viable option for those wanting to keep a stock kernel. The apk wrapper makes it a little more user friendly I suppose
Edit: if I recall correctly it uses Ext2 partitioning

its been pretty well documented that this is a placebo lagfix that just inflates quadrant scores...very very little performance gains over rfs in real life usage
Outdated, and redundant. No need for this thread. A search would have turned this up.
I can personally vouch for the fact that it was not a placebo effect for me. Crazy Quadrant scores aside, I did notice an improvement in performance with it in some areas, and it was definitely a much safer fix than the older forms of Voodoo. However, once the reliable Voodoo 5 came out, this old ext2 lag fix was basically sent to the graveyard. It used a virtual ext2 partition on top of RFS, whereas the Voodoo fix directly converts RFS to ext4, resulting in far better performance all around.

STRONGLY recommend you don't try applying this over Voodoo, since it will try to apply ext2 over RFS and you won't have RFS...
essentially...dont use this...if you want, use voodoo, but not this
I think you guys read into this way too much.
This fix is better than a stock RFS FS. So if you are running stock then this will perform better than a stock rom running RFS.
If you are running a Voodoo fix, then this will perform comparably to that, but you shouldn't use both at the same time, as that would not make any sense. Honestly, I feel like it runs better. It isn't a "placebo" effect, as it just creates an ext2 container to run files from, and is essentially the same thing as creating a partition with ext4 and running files directly from it, without the added functions of the ext4 fs.
I would recommend making some changes to minfree and the task scheduler, however, as that would improve performance and these are functions included in the APK.

Most people that use it say that it only "works" for a day or two, then things start slowing down again. It is also placebo as you have to write to a virtual partition, which then writes to the actual file system, so you're doing two writes rather than one. It's also been seen that it's very buggy and can be problematic to remove as well. You'd be better off installing a voodoo kernel if you want faster I/O, otherwise, you should just stick with RFS.
Alright, so I've been rooting phones for about a year now, but I have zero experience with the Fascinate (have worked on Eris and DInc before now) and my buddy wants me to help him root his phone. I've been reading for a while now, and there's one thing I haven't been able to figure out.
What is the deal with Voodoo? Is there an appreciable difference in performance between a non-Voodoo and a Voodoo kernel? Are there drawbacks to either?
Thanks in advance for any help.
Voodoo is code that is developed by supercurio. There are many branches of voodoo, including color, sound, and lagfix. Each aims to improve upon what Samsung has given us.
Color improves the color contrast of your screen if it is too blue or too red.
Sound is a fix that utilizes the driver inside of our phones to improve gain and give us new options
Lagfix converts all partitions from samsung's rfs file system format to ext4 and yields speed benefits
I am not 100% that my terminology is correct. Please correct me if anybody sees something is wrong.

IMO, voodoo is the only way to go. It is an overall improvement of your phone experience.

So Voodoo kernels contain one or more of these fixes?
Voodoo is basically the conversion of Samsung's RFS file system used in the Galaxy S phones to the more native EXT4 file system.
It also contains improvements such as color, sound, and such.

The only drawback that I have found is that given the slim amount of ROMs we posses here in the Fascinate community.... running a voodoo kernel can limit that a little more.
Also usually when updates roll out from source voodoo takes a little longer to come out.
But in all honesty there is very little in the way of drawbacks. Plus if you don't like it? Flash a regular kernel!
With the recent editions of Voodoo Color and Sound I would see even less reason to not use it.
I like the custom kernels but the voodoo conversion seems to do more harm than good sometimes, are there any cons to just not converting it?
Currently the difference is more placebo than real gain. My suggestion is to clear cache/dalvik and try out stock kernel for a few days, then try a voodoo kernel and compare them day 1/1 day 2/2 etc. I decided to stick with the stock kernel since it was working fine for me and it didn't mess up my screen with that voodoo color crap.
Are you referring to the voodoo lagfix?
No, there's no cons to not using it. I find my phone actually works better with it off.
The only con is that your phone is gonna run slower than it would if it had voodoo on it, also your gonna have a lower quadrant score, but that doesnt really mean anythinng. i dont recommend voodoo lagfix, but i do recommend voodoo sound
Aye, I've been running without the lagfix enabled for a while and I don't really regret it. Much less hassle for a flash-aholic.

I had better results with lagfix disabled on tks kernal aswell. I really dont think ext4 is any faster than rfs on gb... now on froyo roms I noticed more of a difference...couldnt tell you why.
