To subscribers of the xforms list from Espen Sand <espen.sand@neo.no> :

1) You can try to use the shared memeory extrension if possible.

2) Only update the parts you really need to update (if you don't do
that already)

3) There are some multibuffering techniques also, but I have never
tried any of them.

I think the first option is the best (fastet), but, of course, you can't
always use it. The program and the X-server must run on the same
machine.
