Yup, it does!  I've measured 73Mb/sec on my Cisco Catalyst switch with 
TuxType and similar numbers with TuxMath.  Got similar numbers from the 
ifconfig and a stopwatch.  That's why you need 100Mbps/FullDuplex on 
your clients, Gig-E on your server, and a clean, error-free network.

X11 is a wonderful protocol that allows LTSP to exist in the first 
place, but heavy screen updates do eat up bandwidth.
