As you will see when students actually begin hitting that server,
there's no real way to test that kind of load. I did a couple of manual
tests with a dozen or so people when I built my first NetReg box, but it
can't come close to have a couple thousand people hit it at once after
they get their machines booted up.
If it will make your mind rest at ease, I have a PIII 1.4GHz w/
1GB RAM and 2 40GB HDs, and the server load figures never even break a
sweat. My initial NetReg box was a PII 350 w/ 384MB RAM and a 10GB
drive, and I had similar results - you'll be surprised at how robust that
platform turns out.
Have fun...
