Unix is faster at running cvs, because of the way it does things.  On
a same spec machine I'd expect the Linux machine to be about 10-20%
faster (the cvsnt.org cvs server feels faster than the same repository
under NT, even though they're the same code & data).

However a well specced NT machine *should* be faster than a slow Linux
machine, by quite a large margin.

For optimal speed your repository must be on the same machine as the
server, and there should be good communication between the PDC and the
server machine (which speeds up initial authentication).  

Make sure your reverse DNS is working.  If it isn't you'll get a delay
before anything happens.

Use a recent build (there were a couple of speedups around the 57g
time), and enable the LockServer, which is faster than the LockDir
options, and allows multiple simultaneous checkouts.
