It's *got* to be the network configuration on the client machine. I'd be
tempted to install ethereal on the linux box and watch for the
difference between the two networked sessions.

I'm guessing it might be something to do with TCP/IP window/buffer sizes
and delays on ACKs - this certainly used to be an issue on older MS
systems, but I must admit I thought they'd fixed it for XP.

If not that, could some firewall/security system be slowing network traffic?
