Missing benchmark application for Sailfish os

So it would be nice if there is some benchmark applications for sailfish os. Antutu benchmark would be great to see sailfish because then we can compare sailfish devices to android devices.:cool:

Maybe someone become inspired about this idea. There is no any benchmark for sailfish so that's missing application indeed. I'm currently don't have more thoughts about this subject.

I also know that this dream probably not come true.. We have thread for that at least. I hope I caused discussion about this subject, so ahoy sailors speak!;)

Re: Missing benchmark application for Sailfish os

I benchmarked sailfish devices 2 years ago.

Some common linux commands could indeed be utilized by an application and have a nice front end.

~CPU speed

Code:

time $(i=0; while (( i < 999999 )); do (( i ++ )); done)

write speed

Code:

dd bs=16k count=102400 oflag=direct if=/dev/zero of=test_data

read speed

Code:

dd bs=16K count=102400 iflag=direct if=test_data of=/dev/null

service startup e.g.

Code:

time systemctl start aliendalvik.service

Application startup, e.g.

Code:

time xdg-open /usr/share/applications/jolla-camera.desktop

If sysbench is installed even nicer things are possible like:
Multicore/thread cpu test

Code:

sysbench --test=cpu --cpu-max-prime=2000 --num-threads=2 run

Mem test

Code:

sysbench --test=memory --memory-total-size=512Mb run

This only benchmarks the ALU of a CPU, which might introduce a misleading bias.

For example, the first Atom CPUs, while having a comparibly low clock rate, were actually not bad when it came to ALU operations. What made them feel so horribly slow was, that for every FPU operation they needed two clock cycles, effectively halving their nominal clock rate in these scenarios.

A more sophisticated, but still easy to use benchmark would be nbench [1][2]. There should also be some benchmarks for devices like the N900 in these forums.

Re: Missing benchmark application for Sailfish os

Well, there is sysbench like @mosen mentioned
