So, MS wasn't just building eye candy...

I found something in Vista that's a definite improvement. The TCP stack in Vista DESTROYS XP's TCP stack.

Retrieving a 25MB file from our San Diego file server:

Vista - 5 minutes with the defaults.

XP - 8 minutes with tuned TCP window sizing, SACK turned on, and RFC 1323 extensions enabled (which beats the 11 minutes it took with the defaults).

Both are running MTU set to 0x500 (1280), to prevent fragmentation across the VPN tunnel (which they have to, as I've gone over Windows insane setting of DF on every packet in a previous post).
