We don't have any local disk for users on our Unix boxes; users log out
when they leave the room & will get a different workstation when they come
back.  We're going to move Windows to that model too.

A way out from users tied to "that computer" would be a shared drive for
builds of course.  We have gigabit to the desktop.  A local drive, 7200 rpm
~ 60 MB/s which is ~ gigabit ethernet.  100T network is 11.7 MB/s.  Our
server has 10 GB too.  For older windows laptops, a Samba share is faster
then a 5400 rpm local drive.  For 7200 rpm, it's about even.  How much of
your speed up was due to local vs network drives?
