Is xp Pro dual xeon faster with hyperthreading enabled?

Hi,

I have a dual Xeon Windows XP Pro machine with hyperthreading enabled. I
run an application that is specifically designed to run on a dual processor
machine. When I run the application and look at the performance graphs in
the task manager, it says I'm only using 50% of my cpu resources. This
seems like a waste of system resources to me, but I'm so confused about real
and virtual processors that I really don't know.

My computer runs on this software can take over a week to run, so I'd like
to make sure this babys crankin as fast as it will go. If anyone can help
me I'd be very grateful!

thanks,
Bob

The test results I have read show a significant improvement (10% to 15%) with 1 MB or more L2 cache. With 512 KB cache the performance increase is less or there can be a slight performance decrease, depending on the applications.
