Hi everybody,

I'm creating a mathematical application that has a very long calculation period, on windows using VC++ Express compiler + .Net Framework my application need 3min to finish (using the BackGroundWorker that is something like QThread).

Well now I restart my project using Qt4, I created a QThread, but unfortunatelly when I compile it in release mode, the needed time is > 15min, (on Linux and Windows).

So, is there any way to speed it at the maximum, using all CPUs. Is there some QMAKE option that allow this kind of performance.

Absolutely thank you very much for any kind of help,
Cheers,
Louis
