Hi, I have a highly threaded demo app which I run on a PC with XP home (SP1)
and a Laptop with XP Pro (No SP).

The CPU, memory etc of the two machines is similar.

The order of execution of the threads execution  varies between the two
machines - not a problem - but the program always completes twice as fast on
the laptop with Pro as opposed to the PC with Home.

The PC does have more applications loaded which may slow things down, but I
wondered if there are any known software differences between the two
flavours of the OS which might account for this significant performance
difference?

Thanks
