How old is this system?
I remember a few years ago, there was a problem with NIC's on IRQ9...
I don't remember the exact details but we had a customers NIC on IRQ9,
and they complained constantly about the lag. When we finally
discovered that the card was on IRQ9, we went into the systems BIOS
and changed it to IRQ10. After a reboot the speed increased drastically.
Newer hardware shouldn't have that problem, but you might want to try
changing the BIOS setting for that IRQ.

I worry about my child and the Internet all the time, even though she's
too young to have logged on yet. Here's what I worry about. I worry
that 10 or 15 years from now, she will come to me and say "Daddy, where
were you when they took freedom of the press away from the Internet?"
