 First, check a few basic things.  Does 'info' work well on the RISC
 System/6000?  How does X on the PS/2 work when only doing local things?
 What about other RS/6000-based programs on the PS/2?  If everything runs
 at a decent pace *except* things over the network, I would suspect the
 network.  Get a sniffer and trace out the traffic.

 I have mucho RS/6000s, RTs, and PS/2s all pounding a 4MB ring.  'Info'
 on a PS/2 from an RS/6000 is not noticeably sluggish.  The graphics take
 a toll on the PS/2's memory, true, but I don't get anything near a 4
 second/key delay.  No, an Xstation shouldn't run a magnitude faster.
 Check that ring.
