Linpack score

Just did a linpack scan on my JG1 flashed SGS running Lagfix and got a score of 8 Mflops. Is this is a good / bad score?
What are your scores?

8.2Mflops or so on JM5. I don't think anything other than JIT (in 2.2) is going to increase that; lag fixes certainly won't change it.

Sorry but I keep seeing JIT everywhere, anybody care to explain what it stands for and how it all relates to awesomeness (thanks)

JIT Just IN Time
Read on..
Android Developers
Android and me

its not in xxjp3 yet ha? or is it?

Also, keep in mind that Linpack is a synthetic benchmark and doesn't accurately reflect real performance. In fact, code like Linpacks will probably receive the biggest gain from JIT (more than real programs).

I'm using the I9000XXJP2 firmware and I think JIT is broken but I've been getting scores of 13.9 mflops with the lag fix installed!

I don't think it is broken but the dalvik files are not compiled to use ARM v7, cortex a8, or neon optimization.

Without any lagfix?!

You should really give more detail, which lagfix if there was one or just stock froyo from Samsung?

No, I'm sure he's got OCLF. Without lagfix froyo isn't any quickier than eclair as of now. Actually, it's slower. I used to get 2200 points with JM9 + OCLF. Now with JP6 + OCLF i get 1850p.

Do you mean it's slower, or rather that it gets a lower Quadrant score? Those are two entirely different statements. I realize the OP mentions Quadrant scores specifically and I apologize for sort of imposing my opinion, but such benchmarks, especially with such little score difference and such major operating system differences, do not tell you a whole lot at all.
One separate test of Quadrant might bottleneck the entire score, even when all other parts of the system are much faster. Just look at how a simple 'lag fix' suggests the phone is twice as fast (quadrant goes from 1k to 2k) which of course, is not the case. Also look at how Cyanogen gets a 3K score with a simple hack, where the phone speed was barely altered.
So I am curious about real world performances:
Do you still get lags on Froyo?
Does the GPS take only a few seconds to get a fix?
Does it launch apps almost instantly stock or with some lag fix?
Does it feel ultra responsive, as should be the result of using a JIT compiler?
Does it render webpages faster than iPhone 4 like the Nexus One, like it should?
Does it still run actual applications, such as Quake 3, faster than any HTC despite their higher Linpack scores, and is there an increase in FPS since Eclair?
Would love to hear about this!

Do you still get lags on Froyo?
- I think it lags more than last eclair builds
Does the GPS take only a few seconds to get a fix?
- Same as JM9. Haven't played with gps in outdoors so can't be specific with fix times
Does it launch apps almost instantly stock or with some lag fix?
- Same as JM9, or slower. Lagfix makes it ok.
Does it feel ultra responsive, as should be the result of using a JIT compiler?
- No, even though others have said that JIT is on.
Does it render webpages faster than iPhone 4 like the Nexus One, like it should?
- Webpages are ultra laggy when there is flash content
Does it still run actual applications, such as Quake 3, faster than any HTC despite their higher Linpack scores, and is there an increase in FPS since Eclair?
- Don't know

1: yes (when no lagfix applied)
2: yes <5s on warm start, <30s on cold start
3: yes with lagfix only
4:i don't think thats the result of the compiler, just the lagfix but yes, and the JIT does make things a little faster overall
5: no the browser is a bit slow i don't know why. Even Fennec alpha is much faster.
6: yes Q3 is extremely smooth, full details + lightmap, getting 56-60fps (=FPS cap on the SGS), it never slows down
Note that Q3 is using the NDK as in native app. I don't know if Linpack tests native code.

Do you still get lags on Froyo?
Not that i've noticed but I will be installing Voodoo anways.
Does the GPS take only a few seconds to get a fix?
GPS is A LOT better.
Does it launch apps almost instantly stock or with some lag fix?
Certain Apps launch almost instantly where others take a few seconds such as PikPok Games, Fruit Ninja, etc.
Does it feel ultra responsive, as should be the result of using a JIT compiler?
Seems fast to me but only as it's a new install will wait a few days, plus I install Voodoo's fix anyway for the screen fixes too.
Does it render webpages faster than iPhone 4 like the Nexus One, like it should?
No, we have flash it's more demanding but you can set it to be on demand then its just on par with them no major difference.
Does it still run actual applications, such as Quake 3, faster than any HTC despite their higher Linpack scores, and is there an increase in FPS since Eclair?
Not sure but all games i've played are smooth without a hiccup.
hope this helps
1000 in Quadrant and 14 in Linpack

New Froyo+OCLF = 1722 Quadrant
No problems. Gps, camera,market... all is ok.

How are you guys getting such a large score? I'm getting about 1000 and it shows the Samsung Galaxy S on the graph even less (I assumed 1000ish was better than the average score). Or am I using some newer version of the app?? :/

XXJPK with OCLF
I've tested 3 times with Quadrant. Scores: 1550, 1764, 1995.
Phone works much faster after OCLF.
I takes 2 seconds to open a book in Aldiko instead 10.

My galaxy s with froyo, one click root and one click lag fix scores 2029. If i could post a url of the picture i would, but i'm not allowed

ive tried jp6 and jpm and not impressed with either. still getting some lag, even when switching home screens with a live wallpaper.

If you use oclf with quadrant you want get a real result.
What i understand it's one database test that is not real.
It don't do it right. The result is that it seems faster then it is.
Sent from GT-I9000 Jpm OS kernel with z4mod

My quadrant bench mark is 2017.
I've got JPK, OCLF v2.2 and SETCPU installed.

If anybody is interested in a little comparison to the HTC Desire:
1550 on LeeDroid 2.2f (Froyo) with OC to 1153 MHz. Some got speeds upto 1700 with more overclocking, but that'll heat up the phone beyond healthy values, I guess. Do not want to put in a fan there .
So with some optimizations like lag fix and file system enhancement the Galaxy S is a really fast Smartphone indeed, let alone the 3D graphic performance. Cudos!

[Q] No JIT in DK28

So DK28 is supposedly 2.2.1 but I ran Quandrat with the stock rom and it comes up 873, almost exactly the same as Galaxy S 2.1, leading me to believe that JIT is not in the rom. Correct?

I may be wrong but quadrant:
1) Isn't the best way to base performance
2) Doesn't really show improvements that JIT provides
Download linpack if you want and your score should be around a 14 or so, compared to the 8.5-9 on 2.1

Quadrant isn't a real life benchmark, and is highly flawed. Check out Quantum's "warp speed edition" ROM for proof.

I got 1205 with stock dk28 but I have noticed others reporting lower scores. Variability in testing with a bad benchmark perhaps?

I've got 1839 lol... For some reason I doubt that's accurate

I did a quadrant test with a stock epic 2.1 and an epic on dk28 and the scores were pretty much the same every time. The major difference was that the Froyo epic ran the cpu benchmarks much faster but hung during the first I/O test. The 2.1 epic ran everything about the same speed and completed the whole test much faster than the froyo epic.

I also noticed this and posted in another thread...
to quote myself
I was getting around 8.3xx in 2.1, and now I'm getting 13.7xx in 2.2.
(I used the 1506bdf2e04b.update-SPH-D700_DI18ToDK28.zip renamed to update.zip method.)
Saw a video the other day showing a nexus 1 scoring 20+ on 1st run and 40+ on 2nd.. My friends Evo (with 2.2) scored @ 38 or so..
Quadrant still shows me well under all of the 2.2+ phones listed.

I expected a bit more of an increase..
I too am wondering if the JIT was left out of our Froyo (if that's even possible, I'm still a total nube to andriod stuff).

What exactly is JIT, does it speed the phone up?
Sent from my SPH-D700 using XDA App

Just In Time compiling...
From what I know about .Net (I'm a C# coder), it allows for compilation of the app for the specific CPU during the 1st run.
Someone please correct me if this differes from andriod's JIT...

the epic has fast computation hw between the cpu and gpu, it could be the case that the JIT benefit doesn't show in the benchmark margins.
the device is a fast one, all compared.

Quadrant scores

Ok so ive rooted this toy, flashed the 1.2ghz kernal and ran quadrant on it. I hit anywhere from 1080 to 1180. Have setcpu on demand at 800 min and 1200 max so why on earth is my rooted nook color running android 2.1 and a flashed 1100mhz kernal hitting wayyyy higher scores? (Around 1280) doesnt seem logical at all. Specially cause this is an actual tablet and thats just a rooted e reader. Did I do something wrong?
Sent from my SCH-I800 using XDA App

Quadrant is a bad benchmark. It weights i/o far too heavily.
The Tabs RFS filesystems bring its Quadrant score way below where it should be, though in actual use it's very fast.
If you move to EXT4, your Quadrant scores will shoot up by around 80%.
Regards,
Dave

O sweet love of mary. 80% you say. Ok ive seen some posts redarding this ext4 thingymabob. Ill check it out. So if im understanding you correctly by changing to this my tab will perform even better than it does now? Or ill just see a genaric increase on this quadrant test that really means nothing? Sorry im noobish lol
Sent from my SCH-I800 using XDA App

Well, my tab is currently on ext4 and my quadrant scores completely destroys my rfs score taken earlier.
However, that said, i don't really feel any performance improvements except the satisfaction knowing that my toy is now on an open and faster file system as opposed to a propriatory and slower one ;-)

Quadrant scores aren't as accurate as people think you know...
Sent from zombie infested Gingerbread.

There's an app called OCLF that will transparently add an EXT4 area on the RFS filesystem without needing to convert the whole thing to EXT4, giving you EXT4 IO performance in an easily installable and reversible way. Probably your best choice for trying it out. Otherwise, for the complete conversion, you could try this Modaco ROM/Kernel, which includes a complete conversion to EXT4.
As far as performance differences go, it makes a huge (10x) difference to the Quadrant IO score (measured before and after figures), but no measurable difference to actual performance (measured real-world usage figures). Some people claim to notice a subjective difference, but I never did.

Im using the modaco rom and kernel with ext4.
And it does make a huge difference. I get around 1800 in quadrant now.

hi,
please be aware that the modaco kernel (rfs/ext4) will not work on CDMA Tabs.
from modaco kernel thread
This kernel is ONLY tested on a UK Galaxy Tab. It MAY work on other GSM Tabs, it almost certainly WON'T work on a CDMA Tab. If you have a non UK Tab and want to test (and know how to flash back to a regular version), then go ahead and report your results. At your own risk.

That's the point!
It makes a huge difference in Quadrant, which is a synthetic benchmark, but far, far less difference in real world usage - hence it is a crap benchmark!
Pre-EXT4 my Tab would pull around 1000 in Quadrant, whereas my Desire HD would pull around 1800. However in real usage, they seem to perform pretty much the same which is not too surprising as they are similarly specified. On EXT4, my Tab pulls around 1800 now, but still performs much like my DHD.
I so wish people would stop bandying about Quadrant scores because they are meaningless.
Regards,
Dave

If you look at the scores in quadrant , they are split by colour so you can see how good the graphics capabilities are for example and compare to other phones. The colour codes are at the bottom of quadrant by the way

Linpack is a better benchmark. Not perfect, but better

Not really - Linpack only tests floating point performance.

Dave

Wow, I started a heated discussion lol. Well ive downloaded the one click lag fix but have not applied the ext2 tools as yet. Want to do more reading about it first. Obviously I want my yab to be the best it can be but I surely dont want to make it genericly better at the expence of my video grafix as one user said he suffered in that thread.

Taking Quadrant scores aside, when I made the switch from CF-Root to the Ext4 MCK, I really did notice a huge improvement in real world usage. I'm not sure if it is really because of the change in file system, but nevertheless thats the only big thing present in that kernel aside from CWM.

Everything said make sense and seems to be valid but let me share my experience.
I have Samsung Galaxy Vibrant and T-mobile Tab. Now both are using EXT4 file system and have fully functional recovery allowing for flashing straight from the phone.
Both now have Quanrant score around 1700-1800 and run very smothly.
Is I/O speed important? I think it is very important because task switching requires reading of huge chuncks of memory. Until read operation completed the user is essencially suspended. Multitasking is the major distinction of Android and lags associated with the tasks switching might be the most noticeable issue since its used so much. Converting of the RFS file system to EXT4 practically reduced lags to unnoticeable level. I don't need any better.
Another critical area for I/O is playing video and especially capturing HD video. The latter works only if I set internal storage and shut down all tasks.
This is work in progress but it seems it reached level of usability when most critical bugs eliminated.
It should be noted that the Tab is flashed with Rotohammer KM2 v1 ROM and Paul Obrien's kernel on a top. The kernel contains scripts converting the file system and flashing recovery. This combination works well, no issues so far.

Well I decided to give it a try and after install my quadrant is 2556 and linpack is 16.865 mflops at 1200mhz. Good scores but just numbers. I do however believe im seeing a bit of snap that I didnt have before when accessing my library. Still really unsure if this is a good thing as im not sure if I can use apps to sd anymore so I may uninstall at some point in the future but thanks to all you who helped the old man out. Atm im quite happy

Overclocking will raise processor/RAM heat dissipation and thus might lead to a catastrophic failure. It would be great to have temperature sensor on the board or at least measure current consumption from the battery but it is not easy.

Atrix quadrant scores

Hello everyone. What's a good quadrant score for a stock 860? I have been seeing 2600-2650 on average, is this fairly common for this model? Is there a good way to prepare to take the test by closing apps, features etc?
Sent from my MB860 using XDA Premium App

Ive been averaging consistent 2500 of four attempts in quadrant after the 4.1.57 update. I normally run it just after start up and I get those scores.

I achieved 2740 with 4.1.57

I've gotten around 2900 once, but it usually falls between 2650 and 2800. To be fair though Quadrant only tests a single core, if you compare it vs say an inspire on stock rom (Or probably even a custom) at stock clocks it will only get about 1900-2100. So really the Atrix gets 20%-30% better scores and it's only using 1 of 2 cores. Another thing you'd notice on the Atrix is it has nearly no slowdowns, even an Inspire running at a 1.8 OC (battery life is horrible) will bog when you install/update programs while doing something else because it's still a single core and needs to share cycles across programs where the Atrix can devote a core to all background activities and the other to what you're doing in the foreground. I didn't really notice how fast the Atrix was until I had to fix something on my girlfriends Captivate (Gave her mine when I upgraded) and she has like 25 apps and a custom rom with a 1.4 OC and OMG it felt so slow compared to my Atrix.

I got a 2774 with the gingerblur ROM. That's the best I've ever gotten and I've run it on stock, 1.52, the new update and gingerblur. Gingerblur has gotten me, by far the highest and most consistent scores of all. I usually run between 2600-2750 under normal usage, which is quite a bit.

1-what kernel were you using when this 'bog' down happened at 1.8 ghz when something was updating. cause my inspire at 1.8 ghz while downloading a file through web, and updating apps in the market will still be faster than the atrix. ive NEVER even had so much as a hiccup at 1.8 ghz on my kernel, and i just did exactly that, downloaded a file, while 4 apps were updating in the market, and at the same time opened app to qr, and the apps loaded instantly. the atrix takes a few seconds for it to load up, with nothing at all going on, with all bloat removed and only the factory default apps on it. the inspire has over 100. also, i posted this elsewhere also, testing my kernel yesterday running at 1804 mhz all day long, i got over 16 hours off a charge with 3.5 hours screen on time. screen brightness was at 100%. if it was at 50 it could have went much longer. not horrible if you ask me. the inspire with a single core doesnt lag when a live wallpaper is put on it, and i can actually type on the keyboard without having to correct errors every other word cause its lags so bad.
just another note, my inspire rom and kernel at default 1ghz (no overclock) hit 2700+ quadrant

I just got 4000 on CM7

4900 with cm7 + overclock to 1.3ghz ;P
the motoblur software and at&t crap really slows stuff down.
