Re: Benchmarking apps for N900 - How fast is your N900?
 

Running Linux 2.6.28.10power27 (titan kernel) with tonish starving config @1Ghz.

Results : +68% compared to default config.

Re: Benchmarking apps for N900 - How fast is your N900?
 

can someone who understands the data a little better make a simple comparison between various kernel?. i havent been keeping on the bleeding edge with new ones as 800 the mhz kernel works fine for me. im curious if the newer 800 mhz kernels are superior.Ive kinda been not too focused on that cause i wasnt gonna mess with kernels til after pr 1.2 came out, any day now lulz

Re: Benchmarking apps for N900 - How fast is your N900?
 

Some benches / info from me as well, on a fresh booted system:

First off, running @1150MHz the phone reboots. Haven't dared to try higher voltages.
However, Titan XLV @1100MHz is stable, with battery temps at just below 50c:

Running at 1000MHz with lower voltages seems to give 3 celcius lower values to battery.

Re: Benchmarking apps for N900 - How fast is your N900?
 

I just tried the 1150 setting...but ended up with the Error opening file thing.. first time I had seen this.
fyi, I had just put on the applet for cpufreq to try, instead of using the cmd line to input the kernel-config limits cmd.

@1150 settings:

After a reboot, error went away on the slower speeds..havent tried 1150 again yet.

Re: Benchmarking apps for N900 - How fast is your N900?
 

haha segmentation fault at 1GHZ, starving...
time to backup before i break something
this is cool though, thanks

Re: Benchmarking apps for N900 - How fast is your N900?
 

so whats the best till now?

Re: Benchmarking apps for N900 - How fast is your N900?
 

Well, titan's kernel is limited at a maximum frequency of 1150Mhz.
So there's really no way for people to go faster and get higher scores. =P

Re: Benchmarking apps for N900 - How fast is your N900?
 

I'm getting "CPU:NNET--error in opening file!Nokia-N900-51-1:~#" at 900Mhz and even at 600.
Not sure why, cause everything's working flawlessly.

Kernel and settings guideline
 

Yes,
second the motion.

Althought the benchmarks are quite informative,
an 'executive summary' would probably shed a bit more light on the subject
to clarify just what the situation is with the various configs.

something like this, perhaps, keeping it simple I hope.

0. baseline
Stock straight from the store shelf is 500 -600 works ok,
depending on your expectations and firmware update level.
Anybody done any benchmarks comparing PR 1.1 and 1.2 ?

1. Kernel changes
How do the various kernels compare with no settings changes?

2. Clock adjustment
Battery life versus performance.

3. Voltage adjustment
Stability vs battery life

4. Bleeding edges:
Performance, battery life, reliability. (you can have any two of these :D )
The bleeding edge kernel with starvation shows that
the very best that can be hoped for as relatively stable
has about 50%-60% 'general' improvement in speed,
(dependent on the application type of course)

Quantifying the differences show whether the time and risk
is worth the achievable performance enhancement,
depending on what the reader wants to achieve.


Hope this helps. :cool:

Works great @ 1Ghz CPU / 500DSP but dont knw how to copy and past the text. Dont want to type all the info. How are you guys doing it? DOes the result get saved in some folder?

Wouldn't people from cold weather get better scores than people in hotter weather?

Re: Benchmarking apps for N900 - How fast is your N900?
 

Btw, would there be an alternative for this benchmarking that would show more than just numbers? LIke somthing with some flashy graphics and stuff

Very nice thread, thanks Matan for posting the app for Maemo benchmarking.

Re: Benchmarking apps for N900 - How fast is your N900?
 

Kinda, if your from the Uk lol I think you could run your N900 @ 2Ghz lmao. Joke :| On a serious note so long as your willing to do it, I'm sure you'll be fine. **Do it at your on risk** I've ran mine @ 250 - 1000Mhz since a week after I bought the thing. That was before summer by the way, depending on how good the factory build of you exact phone is you can run it @1Ghz I'd like to say from my experiences and have no problems the 1st few time you max out the phone on a emulator you will smell that "Oh ****" smell of plastic. Leave it to cool down then you should be okay to have it run as a default script at boot up, I changed mine so it's continusly clocked @ 500 -1000Mhz, only because i hate the little initiation of the clock speed being cycled up from 125-250. I like it to be snappy and sharp/responsive.

I have benchmarked mine but it failed at the "NEURAL NET :" Stage. Not sure why, anyone ideas?

Re: Benchmarking apps for N900 - How fast is your N900?
 

Change to the folder where the nbench binary is located to avoid that error, e.g.

cd /opt/nbench
./nbench

Re: Benchmarking apps for N900 - How fast is your N900?
 

nbench @ 1.15GHz gave me a segmentation error but got it stable at 1.1GHz.
