SSH GUI slow


I used ssh -X to login and remotely run Matlab. The problem is the
performance is very slow. For example, if I minimize and then unminimize
the Matlab GUI, it takes about 11 seconds to repaint the window. This
happens when I ssh within the same server so the slowdown isn't caused by
the physical networking. Also, as a test I ran Pan and Evolution and the
performance was great - I couldn't tell that I was using ssh remotely
with those
applications.

Is this slowdown caused by Matlab and maybe other programs like it? Is
something wrong with my configuration to cause it to run slowly ?

Any ideas would be appreciated.

Thank you,
Curt
