Hi albert whats the performance like when u visit engadget.com on that rom through the native browser?
[Galaxy Tab  Android Development] caine2it:
Yes for me to, this is what I basically said in my earlier post. Although the overall score in the quadrant test improves from 1000 to 2000 or slightly more, this is only because of a higher I/O speed, all the other performances in the test are shown as decreasing, namely cpu, 2D and 3D. Memory is more or less the same. You can see this looking at the individual scores in the I/O test... So now is it really worth putting this on???? I factory reset and it seems things are back to normal... (I Hope) :rolleyes:
[Galaxy Tab  Android Development] spekesel:
Why fix something that isn't broke? Seriously. All respect to get it to work, but I really don't think we need this.

2e recovery, that is what we need :)

Quadrant Figures

I've just installed this on my Galaxy Tab, and here are the results:

Quadrant, before » after

Overall: 1007±6 » 2262±15

CPU: 1609±11 » 1629±50

Memory: 1685±17 » 1686±14

IO: 684±17 » 6928±100

2D: 200±2 » 200±2

3D 859±5 » 867±4

Conclusion: IO is drastically faster. A 10x (assuming linear scores) improvement.

Other scores are unaffected, within measurement tolerances.

I use xScope browser, and couldn't honestly say that Engadget was notably more laggy than before. It always lagged a bit while still loading. I tried it in Dolphin HD and didn't notice any difference. This is just subjective, of course.

Further, subjectively, no I haven't noticed any difference in normal use either. Perhaps I will over time, but I didn't really have any performance problems with it before anyway.

So, in conclusion, it does what it says it does. Is this a real world improvement? Too early to tell. If I notice anything specific, or if I encounter any nasty side effects during daily use, I'll post here.
[Galaxy Tab  Android Development] jeebspawnshop:
Now that's a good, lucid, informative post!
[Galaxy Tab  Android Development] caine2it:
Can I ask you what rom is on your device? I have the JID where graphic performance slightly decreased using OCLF, so maybe different builds react slightly differently using it???
[Galaxy Tab  Android Development] AlexVallat:
The stock ROM that came with it. According to "About phone", that's build number "FROYO.BUJI4". I think that makes it the JI4 compared to your JID, but I haven't really looked into ROMs at all, so if I've looked at the wrong information, sorry!
[Galaxy Tab  Android Development] clubtech:
OCLF does nothing but improve the I/O speed.

It has nothing to do with CPU / RAM / 2D / 3D benchmarks.

Now, as for the browser issue, i noticed the following:

1) over a fresh install without installing any additional apps, the browser is almost always smooth on engadget.com and other sites. after i restore my apps, the browser starts to lag a bit. it is like that on the SGS as well.

2) If the browser lags, click the power button until you see the power off menu pops, click the back button and voila...the browser no longer lags. that is one weird fix.

Any thoughts on item #2?

How can i install the lagfix?

I have a galaxy tab with stock firmware!

[Galaxy Tab  Android Development] qazzi76:
Hi Alex,

Thanks for for that thorough breakdown.

I appreciate your points

My browser is definitely laggy after the oclf tho..
[Galaxy Tab  Android Development] p0les:
I am getting an error in update.zip while in recovery trying to root the tab. Any hints?
[Galaxy Tab  Android Development] spekesel:
You can't root the tab via OCLF. You have to try to the Superonelick method.
[Galaxy Tab  Android Development] p0les:
Thanks for the tip! :)
[Galaxy Tab  Android Development] AlexVallat:
Real World Results

I thought I'd try and add some figures for real world results. We know the benchmark improves, but does this actually mean anything? So, I looked for something repeatable I could measure that takes more than a couple of seconds, and that probably does significant IO:

Load Angry Birds: (from launch to "play" button appearing)

6.24±0.09 » 6.27±0.05

Load Firefox Mobile 4b2: (from launch to 'loading' screen disappearing)

4.03±0.07 » 4.03±0.10

Incidentally, 4s load time for a browser? I seriously hope this is just a 'beta' issue.

Manage Applications: (from click the Manage Applications button to app icons drawn)

2.42±0.78 » 2.31±0.75

Interestingly, some runs of this test with OCLF installed took 7s, but I excluded those statistical outliers as likely caused by something else happening in the background, despite my attempts to exclude that possibility.

So, in conclusion, sadly, no measurable real world effect at all. If anyone can suggest any other repeatable tests that might be useful, please do let me know. If it takes under 2s though then the measurement error will likely be so high as to make the test worthless, so it has to be something that takes at least that long.

Alex
[Galaxy Tab  Android Development] p0les:
Angry Birds levels load a lot quicker after OCLF on my Tab. Could be an illusion.
[Galaxy Tab  Android Development] AlexVallat:
Maybe I haven't got far enough into Angry Birds, but all the levels I can access load instantly...
[Galaxy Tab  Android Development] AlessandroIT:
It's just placebo..

The galaxy tab doesn't need lag fix!

Keep the good RFS on it!
[Galaxy Tab  Android Development] silver-alx:
Quadrant is so sweet with OCLF :-)
[Galaxy Tab  Android Development] almjroh:
Thanks work on my tap ....2060....
[Galaxy Tab  Android Development] daniel.weck:
I totally agree :)
[Galaxy Tab  Android Development] epakrat75:
+1 - I was surprised, actually.
[Galaxy Tab  Android Development] Ezzy77:
A bit strange that Quadrant score rise from 950 to 1950 is just placebo...
[Galaxy Tab  Android Development] mrzane:
Does stock web browser feel faster after applying lagfix? I'm wondering if browser lag issue has anything to do with the RFS file system.
[Galaxy Tab  Android Development] calin75:
Web browser still lags after applying the fix.
[Galaxy Tab  Android Development] foxmeister:
Not really.

It just shows that the benchmark is a very poor one. It seems that on the tab at least there's no real world performance difference with OCLF.

Dave
[Galaxy Tab  Android Development] sts_fin:
Works like a charm, now the mediascanner works much faster. Apps load faster, and the Notification bar stutter is less annoying, and using dolphin HD the browsing experience is like it should be.

My Quadrant score rocketed from 950 to 1930
[Galaxy Tab  Android Development] sts_fin:
Dave you are wrong, the TAB unit ended the awful lag of the Notification bar (Unlocked Scandic version), The APPS load much faster and the mediascanner takes just 20% of the time than before when restarting the tab.

The OCLF does not remove Raiser, it creates a mirror parition which uses the much faster Ext2 which is used for data/app/settings storage like the normal RFS data storage in to which the data is still mirrored incase you want to unoclf. But the apps and the system uses the EXT2 which in this case boosts speed in UI and Software elements that are I/O intensive (diskwrites and reads).

I have approx 100 apps on my tab and the speed boost in the appdraver is really notable. Also Dolphin HD gains a real speed boost if you use the phone internal memory as the Cache.

What the OCLF does not fix is the crappy code that samsung has put in to their browser, since the laggyness of that app is just bad code. Dolphin HD does now flash without problems, the Samsung browser still stutters and bad.

OCLF also helps games and other apps that rotate lots of files from the Data storage like google earth. Also bigger apps (like opera / firefox / earth) load almost instantly compared to the waiting thats there before the OCLF
[Galaxy Tab  Android Development] AlexVallat:
That was not the case when I measured it. Firefox Mobile 4b2 took 4 seconds to load before the OCLF, and 4 seconds to load after it. How long is Firefox taking to load for you, with OCLF?

If you've got any other measurable rather than subjective differences, I'd appreciate numbers so I can try them myself too. The Quadrant score is so improved I was really hoping for measurable real world effects, but I simply haven't been able to find them yet - if you have repeatable tests that show them, please share.
[Galaxy Tab  Android Development] foxmeister:
I was mostly talking about the Quadrant benchmark, which seems to imply that a OCLF Tab is far faster than a "vanilla" Tab.

However, I've now installed OCLF on my Tab, and I can honestly say that I'm not noticing any tangible performance increase. It's clearly worked because Quadrant is now 2100 but in my real world usage it seems much the same as it did before.

I've currently got around 40 additional apps on my Tab above and beyond what was preinstalled.

Regards,

Dave
[Galaxy Tab  Android Development] daniel.weck:
My AppBrain account tells me I've got about 180 apps (200MB in total, I guess in terms of download size). I notice no lag and no battery-eating in-the-background (especially since the Gallery3D bug has been erradicated ;) ).

Mind you, I've got DroidWall and AdFree installed, to minimize bloatware and unwanted intrusions. I also like to keep the running system lean, by disabling unnecessary pull/push notifications, and by only installing widgets that I actually use (i.e. no weather fancyness on my desktops, I can look through the window, thank you :) ).

I like to keep an eye on what is "active" in the background (whether it is a dormant app or a service that consumes CPU cycles). By default there are a few services on "standby" (like voice search), and the overhead can sometimes be significant.

We hear a lot of buzz about dual-core Tegra 2 -based devices, and I for one am very exited too ! However take a look at the existing reviews and you'll see that it is not all that great performance-wise => the hardware may be good but bloated software and/or badly-configured firmware can ruin the whole experience.

The relatively less powerful Hummingbird does a pretty good job on the Tab, and yeah, it's a phone, and it's also a tablet ! :p (for those who are still trolling about iPad/iOS versus Tab/Android) All these devices are ok as long as they increase productivity and fun in one's digital lifestyle ! Sure, the Galaxy Tab was already obsolete before it was even released, but it's pretty darn useful and fun to use, so I'm not complaining ! ;)
[Galaxy Tab  Android Development] sts_fin:
This is true, quadrant puts too much weight on I/O benchmarks, so OCLF does falsen the statistic.

But like I said before, the OCLF does help in situations that are I/O dependant and in those situations the difference can really be seen.

But yeah you are right, quadrant is not the best benchmark to test what this does.

Oh btw which version of the OCLF did you use? the 1.x? or the 2.x?
[Galaxy Tab  Android Development] sts_fin:
b2 is optimized i tested it with the 40MB beta 1 (the fennec one) it it went from 8 to 4 sec. So I recon that the I/O has got better. (both times I unistalled the app and reinstalled and removed all the cache data)

Im using the 2.x version of the OCLF not the 1.x, since there are two versions in the app this should also be stated.
[Galaxy Tab  Android Development] AlexVallat:
You're right, I should have specified this. I too am using the v2 lag fix, not the v1 one.
[Galaxy Tab  Android Development] Filgaliel:
I have tested this for some days. 3 days of use without the fix and now 3 days with the fix applied. Honestly I did not feel any real difference in my everyday use.
[Galaxy Tab  Android Development] Router:
thank you for the test, great stuff!

Now, my 5 cents in OCLF. Ryan wrote it to improve @the clogging@ in the fs of Samsung Galaxy S (I9000). With time due to the way reads-writes are made and memory was structured on S the "waste" was stacking dramatically decreasing the memory jobs speed. Afaik in P1000 altough it is almost a big I9000, the memory map is different, esp internal memory. Anyway, the tweaked OCLF works on my P9000 like a charm, i/o speed increased, no visible speed improvement unless (i guess) you do something with lots of reads/writes.

Could it improve browsing since i read that a block of internal memory on P1000 is isolated for internet caching exclusively?
[Galaxy Tab  Android Development] Router:
Ryan, 2.2.8 is on the market - got it yesterday.
[Galaxy Tab  Android Development] betoNL:
As far as I have seen so far, and in comparison with the sgs, the sgt works smoothlier, got more available ram,is faster, does not lag etc. etc.......so..... DONT GO LAG-FIXING a device that does not need fixing!!!

Unless you are 100% sure about what you are doing....

Many probs are user-related really.....

And Quadrant benchmarks mean nothing......
[Galaxy Tab  Android Development] deez1234:
Yea my tab runs like butter with no lag fix. I'm not ready to mod to much on the tab yet anyway. Maybe some of the framework or something would be cool but I'm content!
[Galaxy Tab  Android Development] sil3ncer7:
Just rooted and OCLF and its awesome
[Galaxy Tab  Android Development] Justin^Tan:
errrr, can i ask how to remove that gallery3d bug?

mine is eating away the battery
[Galaxy Tab  Android Development] xoltrix2000:
Hello, i'm about to install the lagfix but what's the best size to choose for it? It says 854MB by default which sounds an awful lot of space! I'd end up with only 500bm left for app storage :(
[Galaxy Tab  Android Development] sil3ncer7:
I would buy a 16gb card and set it to 10**. right around the 1000 mark. Thats what I run on both my Vibrant and Tab and havent had an issue.
[Galaxy Tab  Android Development] Croak:
You don't lose any storage with the lagfix...all that space is available, you're just telling it how much of that space should be shifted over to the new, lag-free EXT2 format instead of staying on RFS. In this case, bigger is better. I generally run 1200 on my Galaxy S phone, and that's the same I'm running on my Tab.
[Galaxy Tab  Android Development] le0.br4zuc4:
Can you move apps to SD after the installation?
[Galaxy Tab  Android Development] le0.br4zuc4:
Wow this thing is much faster now! My internal memory is only 230mb why puffs that?
[Galaxy Tab  Android Development] xoltrix2000:
Yeah, but my internal storage went down to 545mb after lagfix. I tried installing new apps after this and it decreased. How do I find out for sure?

How does one tell the app to use the sdcard instead of the internal?
[Galaxy Tab  Android Development] xoltrix2000:
I'm nearing 200mb :( There has to be something wrong that I'm doing.
[Galaxy Tab  Android Development] le0.br4zuc4:
I don't think you doing anything wrong because I'm having the same problem. I would love to get to know how to fix this
[Galaxy Tab  Android Development] foxmeister:
Is it, or is it just that Quadrant says so?

I tried the OCLF and all it seemed to do for me was increase the Quadrant score. I didn't bother reapplying it when I updated my firmware, and I still notice no difference!

Dave
[Galaxy Tab  Android Development] rizdroid:
I've applied OCLF on my SGT and it seems faster now. Here are a couple of screenshots: http://goo.gl/S2abu
[Galaxy Tab  Android Development] betoNL:
I have myself a SGS, but I was playing the other day with the SGT of my neighbour and it was smooth, fast and responsive.

If your device is not lagging, why would you apply a lag-fix converting the file system and with potential side-effects??

And about the RAM, do you use the stock RAM manager (inside stock task manager)

to clean it?

And why are you asking for donations?

« »
[Galaxy Tab  Android Development] jokerls240:
Just my humble opinion and theory:

The SGS runs on Android 2.1, and the SGT is using 2.2. When I had the OG Moto Droid, 2.1 made the phone unbearably slower than 2.0.

Theory: Froyo (2.2) has some performance tweaks over Eclair (2.1), other than the obvious improved UI features. Seeing how we have 2 different OS versions between the SGS and SGT, comparisons in performance with bone-stock software are flawed because, as required for any experiment, you do not have any constants - only variables.

On the other hand, comparing a stock SGT to a modified one gives you a constant to work with. The only problem with US Tabs is the various bloatware installed by the respective carrier. Also, as stated before by many people, including devs that have been working with Android since the G1, Quadrant scores are very subjective. While it is a reletively good benchmarking tool that tests various areas of hardware & software integration, any given score can be improved overall by just tweaking one aspect of the hardware/software integration (or communication).

While I commend,respect, and understand Ryan's work, I feel that OCLF is not required for the Tab. My VZW Tab is still stock and is a lot faster in some areas than my stock DI01 Fascinate. Of course the lagfix improves Quadrant scores significantly on both devices, but only in the area of I/O and database read/write. This can translate into apps loading and caching faster and that's about it. Those of you using Apps2SD should report any difference between pre- and post-OCLF, as I'm unsure how it could improve the performance of loading an app into the EXT2 cache from external storage, or if the fix even supports that.

With that said and from the bad experience I had with OCLF and the Voodoo lagfixes, I'm keeping both devices stock with the exception of possibly rooting the Tab. The Fascinate is waiting for DJ05 before root, CWM, and jt1334's kernel and CleanROM. Then I will wait to see what improvements Froyo brings to it.
[Galaxy Tab  Android Development] betoNL:
Mostly correct except for the fact that most sgs devices are running froyo 2.2 already. Official upgrades available in many regions.

Other thing, some modded Kernels are pretty fine and I am glad I got around 40 MB extra ram with Hardcore's speedMod Kernel (total 341 MB. still much less than the Tab).

And NO Lag-fixes....
[Galaxy Tab  Android Development] ATom_:
lagfix

I have 3E version of the system recovery. Is there any OCLF available for this?
[Galaxy Tab  Android Development] heygrl:
Why would anyone install this garbage on the Tab? It doesn't have lag.

RFS is not the reason for the "lag" on the Galaxy S. The Tab is proof of that. Same file system, and it runs so damn smoothly. What's the excuse or reason now? Maybe something else that makes no sense?
[Galaxy Tab  Android Development] jammysunny:
Hi @All,

Do Someone know, which original Firmware is the German unbrandet one?

I really need help, `cause Medimarkt must send it back to their shop, it`s a hardwareproblem......

I flashed JK5-Firmware, was really easy, but no Simcards are now accepted.....to not loosing the warranty, I must reflash it to the original firmware....

Please HELP,

greetings from Germany, Karlsruhe;)
[Galaxy Tab  Android Development] betoNL:
Not sure anymore(dont have a tab) but I think the tab got more RAM available....
[Galaxy Tab  Android Development] jammysunny:
Lagfix, Flashback to original=big problem!!!

Hi @All,

i tried to flash back to the original xxxxJID, but the problems begins since i tried to flashback....

I tried to do a factory reset, nothing goes, tried to do the flash with "repartition and so on, nothing still goes, now after three hours, same page after reset:

e:cant mount /dev/block/st110

(invalid argument)

e:copy_dbdata_media:cant mount dbdata:

your storage not prepared yet, please UI menu for format and reboot actions

copy default media content failed.

The first time, i forgot to remove my sd-card, it was the same mistake like the samsung galaxy s,but no problem with sgs, only now with the GT......

the same with flashing xxxJK5, with pit1.....

maybe someone can help me, i must get the flash of JID right, because of hardwarproblems and the warranty, i must send it to repair......

hopefully, jammysunny
[Galaxy Tab  Android Development] patomas:
Try

I had the same. I had to flash before JHA firmware repartitioning with 909 pit.

(If the pit file doesnt work try another but JHA its important, it's a full firmware).

After that you can flash JK5 without repartitioning (and I think it's important without repartition)
[Galaxy Tab  Android Development] p0les:
My Tab certainly feels slower after the update without OCLF. Will use it for a bit before enabling OCLF to see if there really is a difference.
[Galaxy Tab  Android Development] ayman07:
I initially installed the OCLF because of the browser. After installing it i didnt see any difference in the browser but it made my tab so buggy and slow. Only with this "fix" did i get random reboots and overall just feeling so slow. I installed the latest euro firmware which fixed the browser. I uninstalled the OCLF and couldnt be happier. Thanks dev for your work....but im passing.

i guess it all depends on the personal experience of a person for some it seams faster and for others its not as i can see from all of your feedback. any way tomorrow ill be getting my Tab and ill be in the game
[Galaxy Tab  Android Development] mmathai77:
i WOuldnt recommend this, so far it just seems like it changes the benchmark scores.

My system got extremly laggy and twitchy, and unresponsive after doing this. In the beggining I noticed a difference, but after a little while everything got worse, even the starting animations were getting glitchy.
