That is an interesting clarification that you made... it really confuses 
your original question quite nicely.

MATLAB isn't available as an X app on top of Windows, so you obviously 
must be running it remotely.  In addition, XFree86 for Linux and 
Cygwin/XFree86 are completely unrelated as far as performance is concerned.

Are you still also saying that the same remote app (MATLAB) displays 
more quickly using Exceed than it does with Cygwin/XFree86?  If so, then 
my original reply (which you didn't have yet when you wrote your first 
reply) still applies.
