[Interest] Benchmarking machine cpu power

[maitai at virtual-winds.org]

Hello,

I have an application which can be very cpu-intensive, depending on some 
options that play on the precision of computation (you can't expect the 
same precision in the same time on an Android phone or a multi-core 
latest cpu generation desktop).

Ideally, I would like the application to tune automatically these 
options based on the ranking of the machine cpu-wise, let's say "slow", 
"normal", "fast".

I will probably write my own small cpuTest routine, but I was wondering 
if there is something in Qt that could return such a benchmarking 
result?

Thanks
