I've got a computer with two OS'es installed - ASPLinux11 and WindowsXP SP2. I've tested recently a super_pi mod 1.4(pi caltulation) on both operating systems (I've used same Win32 binary file) . It looks like it works faster under Linux, while it crashes under windowsXP at certain conditions. What's going on? My friend tried same trick on his computer(taht is much more powerful). He got slightly different results. IN his case program works fastr under windows, when calculations aren't very complicated (pi with 16K digits), but it works faster under linux when calculating "pi" with 1M digits. What's going on? I just want to know if this is a proof of WindowsXP being slower, or does that mean that there is some timer-related bug?
Calculating PI is not a representative OS performance test at all, since it doesn't involve actual OS facilities and mostly uses CPU math power only. -- Dmitry.
