Hi everybody!

I am new to this forum, so ...

My question is about prime95 stress testing (but also more general):

I have a duallie (Athlon XP 1800+, non-modded) running WinXP SP1 and if I start two stress testing instances every gets 50% of the system - so one instance pro cpu. Everything okay!

But if I start 4 instances then I would expect every instance at 25% of the systems resources.

Mostly this happens - but sometimes I get one instance taking 40% and every other only 20%, or so.

Once it was very extreme: one got 50% and every other only 17% of the system.

This problem is not only occurring with prime but also if I am starting SMPOV with 3 or more instances in order to run multithreaded POVray renderings.

I think the scheduling of WinXP pro is not so perfect ...

Any suggestions why this is happening?

(Of course I know I could set affinities in Windows TaskManager)

greetings stippix
