Hi,

I have been running SETI@home for a few years now and only since I

installed

Windows XP Pro have I been able to see the amount of process time the
application receives. It's only 50% and the other 50% is "System Idle
Processes."

What gives??

One scenario would be: You're running a single instance of the Seti client
on a HyperThreaded enabled cpu.

If that's the case, your single client will run nearly identical WU times
with or w/o HT enabled.

If you run two CLI clients w/a HT system you will see your WU times increase
by ~40 - 50%, but will process 2 units in that time period, for an aggregate
increase in production of ~50% for your machine; i.e. if your currently
producing 10 WU/day w/1 CLI, you will produce ~15WU/day w/2 CLI's. If you're
currently using the GUI client & change to CLI's,  your increase will be
even more substantial. If you're running a single instance of CLI 3.08 &
convert to CLI 3.03(s), you will see an additional ~ 10 -15% increase in
production vs. the CLI 3.08's

If you have a reasonably quick HT  machine [2.6G+], & a decent graphics
card, you can easily run two CLI's, & still use your machine for moderate
general use w/o too heavy of a performance hit.
