Why do you use cmw 2.5 instead 3.x? Major of mods run under cmw 3.
[Galaxy S I9000 Android Development] gsw5700:
I think ext4 (with journal) reads at about the same rate as ext2 but ext4 is twice as slow at writing (as it has to write to the journal - more wear, more battery).

On Speedmod 13E, I set my cache (only) to use ext4nj (no journal) and I got something like 200-300 extra on quadrant) and the phone DID feel more responsive.

This may be a good compromise for hardcore, allowing us to have the cache on ext4nj

and run the rest on ext4.

If you run ALL on ext4nj, then the phone will really fly...

Will you still continue to develop Kernels for SGS if ever you get your SGSII?

Anyways, i installed this on Stock Deodexed JVP and i am very satisfied. First time Speedmod user here!
[Galaxy S I9000 Android Development] spambayes:
First, thanks to Hardcore for making this available. Have run Speedmod since Froyo and it's been a blast.

Now I'm on stock JV9 and T5 (just upgraded from T4) with no lagfix. My Quadrant score remains between 1000-1050. I know that Quadrant isn't the most accurate benchmark around but I routinely see others having the same setup as me posting at least 1300-1600 so my scores are low in relative terms; I would like to find out why that is so and improve on it.

Any ideas?

Thanks.
[Galaxy S I9000 Android Development] hardcore:
The /cache is already in ext4nj to allow for bigger Market downloads. It's been that way since the Froyo days.
[Galaxy S I9000 Android Development] whaave:
If you feel your phone is fast, smooth and snappy, why bother with Quadrant? Quadrant does not reflect user experience.

If you want, I can photoshop a screenshot of Quadrant for you, showing a score of 15000. Would that make you feel your phone is "faster"?

One easy way to improve Quadrant score is by setting all the stagefright settings to 'true' in build.prop. But that breaks some video playback. Or you could overclock your phone, but that reduces battery life. Or you could place all the Quadrant files in a 'RAM-drive', but that's a really inconveniant way of booting your phone. Would any of these be worth a higher score?

I have a problem whit a bootanimation.zip in /system/media = bootloop :eek:
[Galaxy S I9000 Android Development] spambayes:
It should be obvious that my aim is not a higher absolute number but a real-world improvement. That is why I emphasized 'relative terms'. It does not matter if I felt my phone is fast, smooth and snappy enough. With no basis for comparison, the frog at the bottom of the well thinks he can see the entire heavens and has no cause for complaint. But many of us who come to XDA come at least in part for the purpose of learning enough to max out our phones in terms of performance and Quadrant may provide a convenient basis for relative comparison if used within accepted limits.

I could not care less if my score was 1 and everyone else's scores were in the ballpark. But if there were a marked discrepancy, it behooves me to ascertain whether the reason lies in some real deficiency in my setup or whether it is because everyone else photoshop their Quadrant screenshots. If the former, I would like to rectify the problem; if the latter, well... I still have enough faith in the general level of honesty to be found on XDA.

Thanks.
[Galaxy S I9000 Android Development] DocMarc73:
Stock jvp, about 150 apps installed, just speedmod kernel and ext4. Nothing magic, it was just the second run! ^^

First run about 1800.

Must admit the phone is pretty responsive but doesn't feel double responsive as with 1000 points, because quadrant doesn 't measure the latencies which are more important for the everyday usage and which are responsible for the responsiveness.

Rrrright? ^^

Hey thanks for the quick update to 2.3.4 kernel modules...

seems much faster without lagfix... I am using stock DDJV6 with ur kernel....

and Can you update the source for the latest version you released ?

Thanks in advance...
[Galaxy S I9000 Android Development] kitkitfok:
Why don't use CWM 3 or later?

When will you release cappy version of speedmod?
[Galaxy S I9000 Android Development] gsw5700:
Quadrant Scores

Agreed...!

You have a "baseline" to see if your phone is 'generally' faster or slower after making a change (Rom/Kernel/memory setting etc). We don't have access to complex test software simulating real life scenario's so have to rely on quadrant which is fine. If you convert file systems to ext4 you get a higher score, convert to ext2 you get an even higher score. So improvements are related to real world facts regarding Linux tuning.

Regarding your own quadrant score.

Remove all bloatware (inc services) you don't want the CPU ticking along at 10-20% running background/system tasks.

Ensure you are running the ondemand govenor (up_threshold=50)

Ensure you are using ext4 file systems.

Check the virtual memory settings (standard 2.3.4 look good)

Test the deadline scheduler.

Always run Quadrant using the same way so results are consistent'ish.

I wait until the phone is quiet, and run quadrant 3 times, the last run is generally the best as data is cached.

Hope this helps

[Galaxy S I9000 Android Development] dherre65:
Hi Hardcore, I was wondering why the system partition is not converted to ext4?
[Galaxy S I9000 Android Development] mialwe:
This kernel is running great with JVP (as id did with froyo-version on froyo btw), just one question: As the cwm option to enable logcat is missing in this version is there any way to reenable logcat via adb e.g. for app developers?
[Galaxy S I9000 Android Development] DocMarc73:
It makes no sense to convert system fs, as it 's supposed to be read only. So ext4 wont speed up anything because it accelerates mainly writing speeds.
[Galaxy S I9000 Android Development] jlsesler:
Please release a captivate version. Pretty please!
[Galaxy S I9000 Android Development] domin0311:
yes captivate version would be nice
[Galaxy S I9000 Android Development] russell.nash:
@hc: this is just an informational question. Being on stock JVP, ext4 converted on CFRoot and then speedmod flashed over. Interestingly the quadrants on CFRoot are around 10% higher. It looks though that the 3D tests in quadrant have significantly higher FPS on speedmod, whereas the IO test looks slower. Are there really the same ext4 mount options in CFRoot? Though being really faster in 3D you loose overall 10% with IO. That reads like a field for possible improvement.

Just a note ...
[Galaxy S I9000 Android Development] dherre65:
I do not at all experience this. with speedmod i got multiple times at around 2140 points at quadrant and now at cf root exactly the same.
[Galaxy S I9000 Android Development] yc1437:
Just to share my finding, do not flash T6 on 2.3.3, it will lag your system. Use T4 instead.
[Galaxy S I9000 Android Development] gsw5700:
How scary is that, I've just gone back to t4 as this felt the quickest, and seemed to use less cpu, will keep an eye on it
[Galaxy S I9000 Android Development] jaiiscool:
Can someone tell me what are the default minfree values on T6, i have messed them up.

Thanks!
[Galaxy S I9000 Android Development] russell.nash:
The story is not only about the total quadrants but also about differences in 3D and IO part of the test...

Anyone knows how to reenable logcat for app dev purposes? On Froyo this was done inserting logger.ko if I read the sources right, on T6 I cannot find a logger.ko...

[Galaxy S I9000 Android Development] lpy:
In reference to Quadrant with 2.3.4, a couple of things to note...

Stagefright is what's boosting the score, and even more so with the charger connected.

You will notice it affects test 1/10, H.264 - it almost looks like it bypasses it altogether...either that or it's stagefright's performance boost in effect.

My setup with SpeedMod, JVP 2.3.4, and OC @ 1.15GHz, RFS, charger connected, after a few Quadrant tests,

Stock kernel: ~1590

SpeedMod: ~1700 (slightly up in CPU)

any feedback on T7

i did a fresh install before coz of other mods i added and hated

i tried t7 on ext4 and it was really laggy, quadrant was 1600 but it meant nothin with how slow my phone was

ive just done another clean install from eclair, to froyo, to jvp. wiped everything and im wondering which version to flash now

anyone have thoughts on F1 Rom and darkcore kernel?

HI,

I just installed T5 over fuguroot(stock DDJV6 over fugukernel).

Apart from it I havent installed any other mods and running stock DDJV6

Problem is I am not seeing any changes to Quadrant which was 1050 on stock and now it is 1080. Nowhere near 1500-1700 which people are reporting.

Why is that so ?

Plus, I just confirmed Auto Brightness is not working
[Galaxy S I9000 Android Development] demonstone:
maybe is stock rom issue... have you noticed that all people who says that autobrightness works well are on criskelo rom, aren't they? mmmm....

[Galaxy S I9000 Android Development] SaneinOne:
I flashed your T6 to root and agree that auto-brightness seemed disabled. Locking and then unlocking device would temporarily restore auto. Then flashed back to stock it resolved issue.
[Galaxy S I9000 Android Development] SaneinOne:
P.S. Enough with all the Quadrant scores, it's not an optimized benchmarking tool for the SGS.

Hardcore, you're right, I tested it based on your remarks and it's works. Anyhow I quite like it this way ... just need to switch screen off and on to change brightness, cool :)
[Galaxy S I9000 Android Development] tzyn:
I can confirm that.

JVP flashed and tested darkcore and speedmod kernel. Today (with DarkCore 2.7.3) I noted that in bright environments the brightness doesn't changed - only with screen off and on. I tried Speedmod kernel and got the same problem. So i thought it's a JVP problem. But now i tested supercurio's kernel and it work great.

So:

speedmod t6/t7 - doesnt work!

darkcore 2.7.3 - doesnt work!

supercurio stock+hacks - works!

Hmm looks like auto brightness with JVP doesn't work properly because Samsung must have changed something in the kernel source again and haven't updated it yet.

This is probably the case unless someone manages to compile a kernel from the last source release that has auto brightness working.

Hey hardcore, I am not sure if this is a kernel issue or just my issue, I am just putting it out there. I flashed stock JVP, flashed your kernel, then restore apps + data from titanium. Seems that some games hangs randomly, it could hang while in game, or hang while on introduction screen. Some games are like plants vs zombie, shadow guardian, angry birds, possibly happen on random games. I need to hard reboot cause I the phone just freezes. This also happens on stock rom.
