According to several sources I found, the SUN X server is not only
unoptimized, but de-optimized (HP and NBS).

This depends.  I have an HP350 with the TurboSRX graphics accelerator.  This
is one fast X Windows device!  Even considering that I have a beta-release
of the HP version of X11, we are talking refreshes at video sync rates.
The SUN X11 is pretty worthless in comparison.  In addition, the SRX can
be set up with X running in the foreground planes, with the background
graphics planes reserved for Starbase (HP graphics library) calls.  This
feature (supported as an X windows subroutine library) will give you animation
speed in 3D...
