I thought that I would repost, in case somebody missed it. Is *anybody*
looking at this? Or, is it proprietary?
------------------------

Has anyone looked at the relative differences in performance between an
X based windowing systems (like, DECWindows, OPEN LOOK, or Motif) and
Presentation Manager under OS/2. It seems that X is going to be slower,
given the overhead of a networked environment, but has anyone examined
this with a test application or benchmark that they can share their
findings? Is it a few percent or an order of magnitude? If I am thinking
about PC's versus X displays (where client and server are on different
machines), is the performance difference going to be enough to sway me
towards buying an OS/2 "workstation" rather than an X display (ignoring the
difference in cost and availability, or lack thereof, of applications)?

Any enlightenment is most appeciated.
