Quadrant scores

[conan1600]

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?

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%.

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

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 ;-)

Ok so ive looked at some threads containing info but I see no post telling me how to do this magic. Could one of you nice, young, kindhearted souls link me to where I need to go to put this thing on my verizon cdma galaxy tab? Please and thank you sirs?

Quadrant scores aren't as accurate as people think you know...

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.

mike

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.

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

 

[foxmeister]

Not really - Linpack only tests floating point performance.

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.

More reserch required

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

Now lets get ta craka lackin on a 1.5 ghz update for our tabs

Of course you can use a2sd. Froyo does it by default

I think you are pushing!
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.

 

[conan1600]

Of course im a pushin lol. Only way to achieve is to try. Course ive read about the tab proccessor being able to handle 1.4 stable and can handle 1.6... Not that id know about these things first hand. Just taking the words of better men.

Just an old man with a little time to kill and a dream to be able to play facebook cityville on my tab haha. Well that and I have always enjoyed souping up my toys lmao.
