Well, yes, we have a fair amount of experience running X on an SRX :-)
From the performance comparison you posted I would guess that the 340
has a "CH" (i.e.  98550A) display card.  The "CH" display system has
several hardware features which are quite useful for the X server, and
that the SRX lacks.  Given equal levels of software tuning, an X server
for a CH will be quite a bit faster than one for an SRX.  I am, however,
surprised at the ~3x difference you are seeing.  It may be that you are
hitting an unusually bad spot in the SRX server.  Is there any chance
you could make available a sample program which demonstrates this level
of difference?  An executable would be fine.  I can't guarantee that we
can offer an improvement, but I'm certainly willing to take a further
look at the problem.
