X-Windows Performance, or lack there of?

Ok, a friend of mine has an Alpha, running Squeak, he is displaying the 
X-Window head on his 450MHz Windows NT box. The Alpha has a load of 1.48. He
is using Exceed as the X-Terminal Server on his NT box.

His complaint is:

> Start Squeak.  Wait for screen to fully refresh.  Then choose menu item
"refresh display".  It takes eight seconds to refresh.  I can watch the
browsers redraw.

Ah, this seems excessive? I've seen lots of comments about X-Windows
servers, accelerators etc float past in the last few months, without having
too much of a need, but now of course I've a friend with a question....

Why so long and how can he fix it?

I gather raw horsepower isn't the problem here, rather bits, lots of little
bits on the wire?

His Alpha does
22598870 bytecodes per second;
1288984 sends per second

His NT box does
21304926 bytecodes/sec;
1269320 sends/sec

{Quick which cost 20x as much to puchase?}
