Task Manager CPU Usage History

Guest

I have an executable file compiled in C that does numerically intensive
calculations that I use as a benchmark of computer performance.

I am running Windows XP Service Pack 2.

When I run it on one computer Task Manager shows a CPU Usage History of 100 %.

On my computer at home Task Manager shows a CPU Usage History of 50 - 51 %
only with "Idle processes" making up the balance.

System Properties >>> Performance options >>> Prcessjor scheduling is set to
best performance of programs.
System Properties >>> Performance options >>> memory usage is set to best
performance of programs.

The one at WORK is a 1.8 GHz Centrino processor.

The one at home (that only shows 50 % CPU usage) is a Pentuim 4 2.4 GHz, 800
MHz FSB chip."

Both are single core chips of course, and the executable runs on a single
thread.

Does anyone know what is going on and why I can't get the CPU to work 100 %
on my executable?

Thanx
Doug

Doug, check in Device Manager under Processor and you will probably find that
your P4 machine is dual core, hence the 50% ...
