X is very sensitive to latency as well; we designed X for high speed
(of the day) campus scale networks. ISDN and dial up lines therefore
suffer both due to limited bandwidth and large latency, not a good
situation.
Running Xft based applications (e.g. Gnome 2 with Xft and KDE 2.2 or
later with AA fonts turned on), may perform better, as one of the killers
is round trips for font discovery, which Xft/fontconfig makes a thing
of the past. Keith and I are working on getting some more recent
data of what is actually going on on the wire with the render protocol
changes for Usenix next summer (just got our first data today, as a matter
of fact).
Mozilla/Netscape is a prime offender, enumerating just about all fonts
and retrieving metrics for them all; again, if you get the most recent
Mozilla beta test built with Xft support, this should be avoided.
