The 3.6 millisecond figure (round trip using TCP) between two PMAXen on a local
net was measured with the x11perf
program, which you can get off of expo.lcs.mit.edu or gatekeeper.dec.com.
It is performing a no-op X request, and timing the response (I think it
is just measuring elapsed time on XSync X library calls.).

The current version of x11perf is version 1.2.  It will also be on the
X11R4 distribution.
