I have the captivate with bloatware removed, unhelpful's overclock kernel, and the lag fix, I get quadrant scores as high as 2505. I was wondering if the phone its just that awesome or if there were similar mods to snapdragon phones that give them similar performance. i know they can be overclocked.
I guess what I'm getting at is that my phone would hang on the file system tests in quadrant until the lag fix where the score nearly tripled! Is this something unique to the galaxy s do to a flaw or are there similar problems on other phones that could be fixed and yield similar performance to my phone? Or is the galaxy s cpu, gpu and ram and other components just that much better?

My $0.02 says the galaxy s as a processing unit is slightly better than the older snapdragon. Better optimised, newer (45nm > 60nm) etc. There could very well be processing issues on other chips too. We wont know until someone finds them. Bear in mind however, the Snapdragon chips are likely to be much better optimised for android operating systems - as android is developed on that reference hardware - e.g. nexus one uses a quallcomm snapdragon and gets a massive jump with JIT, froyo. However, droid X, Droid 2 with froyo dont see nearly as high increases in performance.
The GPU is known to be significantly better on the Galaxy S phones. However, its only a matter of time before the next gen snapdragons take the lead again (or at least play catch up)....and somehow I wont be surprised if the subsequent Galaxy S 2 devices retake the lead
Pretty much what I was thinking, from what I understand the snapdragon has up to 20% greater throughput than a standard arm v7 processor but the hummingbird needs 15-25% fewer instructions to do the same task. I wish I could remember the reference for that. In other words, snapdragon works harder and hummingbird works smarter.
I knew as far a shear performance it would come down to the gpu but didn't know any details on that.

The issue that slows the Galaxy models is Samsung's proprietary file system. The lagfix improves performance by wedging in between the filesystem and providing a buffer built with a modern filesystem.
The massive score increase in Quadrant is due to the file IO being MUCH MUCH faster when the lag fix is applied. If you were to look at the professional version of Quadrant (which breaks down the scores into their categories) the File I/O portion would be in the mid to high 6000's, which really unbalances the score..
Is this the future for the Note aswell, the Linaro Kernel??
I would love to see this on the Rocket/Stunner rom

See in the Redit thread that it is incoporated to CM9 and AOSP (Partial)
http://www.reddit.com/r/Android/comments/usuym/linaro_build_optimizations_that_can_make_ics_30/
That looks awesome...
Fingers crossed for a port
Sick! Looks very promising
It is good thing to know that some of the implantation and optimization is ported to CM9 kernel.
It's not just kernel, it's userspace. In fact, compiler optimizations applied to the kernel have been shown in the past to give little more than stability problems with negligible performance increases.
Expect an increase in SoDs, crashes, and general instability as this merges.
Also don't expect the performance improvements to be as great as they've been made out to be - they were highly synthetic, I believe a lot of stuff was in software rendering mode without hardware acceleration. hwaccel nullifies many of the software improvements.

so its not all its cracked out to be, will it be merged regardless and is there gonna be a choice whether to use it or not ?
It's awesome, looking forward to it.
The effects aren't very dramatic. Apps open a smidge quicker from a cold start. The app drawer takes maybe a second less to load everything up from a fresh boot.
The performance increase isn't very noticeable.

Any increase is a bonus seeing as the Note isn't completely lag free. I for one would immediately convert to a ROM based on this.

CM9 is already 30-50% faster than stock, so the increase will not be shocking imo.
And no need for more SOD`s
sounds good, but Entropy512's comment deflated my balloon of high hopes from Linaro

So why merge it in the first place? I mean there's currently no solution to SoDs, won't including linaro make it even harder to solve the problem?
im for stability

its actually working
They managed to make it work on cm9 for galaxy nexus
http://forum.xda-developers.com/showthread.php?t=1700442
so i hope to see it soon on any galaxy note rom

I'm pretty sure they will release it for the Note.
We just have to be patient.
hi, could someone please post benchmark results of the nexus 7?
I am particularly interested in I/O benchmarks such as Androbench and RL Sqlite benchmark.
I want to know this because Asus is having problems with I/O performance on its transformer line on ICS which causes loads of lag and ANR messages....
thanks in advance
I posted mine here
thanks.
the scores on the nexus 7 are way better than on the prime.
did some research and it seems the nexus 7 uses the same memory as the transformer prime ..
http://www.jactron.co.uk/products/e...e-mlc/commercial-grade-25C-+85C/kingston-emmc
must be a software thing ......
Only thing I can think of is the crap 2.6 kernel on the 201, cause both are stock aside from my cfq scheduler on Prime. I thought the T30 was supposed to be better than the T30L.
yea it must be. have posted this info to motley kernel thread.
found the n7 kernel source in his GIT. maybe he is already looking into it or he is developing a N7 kernel too
he is developing for N7. just take a look at the Nexus 7 original developement section. he already has made a sick motley kernel for this device. overclocked to 1.6ghz. happy to see familiar faces over here also. hopefully we ALL can have a better asus experience here..lol
Any update on this? These are my quadrant, IO are the lowest it seems

Hey guys.
Can someone with an Exynos Note9 test out Dolphin's performance?
As far as I can make out, previous phones with Exynos were missing important OpenGL drivers, or the kernel was out of date, or something. This caused Dolphin to really struggle.
The Snapdragon variants of devices never had this problem.
Samsung is making a big deal out of having Vulkan support, so does this improve Dolphin's performance?
Yeah some one try.
The Mali GPU has less benchmark school than even SD835 which came Last year thought.
can you answer this question about dolphin on exynos please ?
I've always wondered that apart from the obvious hardware differences which contribute to the speed difference in phones like OP7P or ROG2 etc (Storage Ufs 3 vs 2.1 in K20P),
-- what's the secret to their software optimisation too?
I've seen benchmarks on custom roms vs stock miui & the difference is visible but not much & even custom kernels have a boosted score but they are still coming only close to or slightly exceeding stock OP7P scores.
In games like pubg there is significantly lesser jank & microstutters on OP7. How come?
Are the driver's much updated or tuned or the cpu scheduler tunings very different in their base software stack?
Pubg in k20pro has a much higher frametime average & level of frame drops vs OP7, especially visible with multiple squads nearby (in-game I don't think UFS3 has a significant potential of impact once assets are loaded in the game but maybe I'm wrong?)
(In general games have better stats when tested using profiling apps on OnePlus vs K20/Mi9T)
What prevents our phone from getting to that level of fluidity?
Atm I'm using immensity kernel on miui 11 & I see it's based on caf sources & there's noticeable performance boost in scores as well as real life usage but importantly the idle drain or drain while using light apps is damn low too!
For example I've not seen <150ma live drain in simple apps or in idle on stock kernel or like on Quax which is based on stock but in Immensity I'm often seeing as low as -95ma-115ma drain which is very, very good & sign of tuned cpu schedulers & other things despite using the same rom.
^^---So is this the sign that the 855 chipset is not fully utilised/optimised by Xiaomi yet?
Even black shark 2 has lesser jitter & smoother operation in daily usage (yes it has the 855+ but it's ~15-20% faster ., seems to have much better base software!)
Can we hope things will improve officially? Or Xiaomi won't prioritize base phones that much vs their 'gaming' phones?
Personally I'm hyped about PapaSmurf kernel coming for our device too! (og made for Razor phone) :fingers-crossed:
*Rumored to come this month (or maybe in Jan!)*
(Mad props to devs like UtsavTheGreat, Xenix96,AcerVenky etc who have developed some really great kernels so far & given their precious time to the community!) :highfive: :angel::good:
