For starters, be sure you are linking with -lmalloc.  This is a big win
for memory performance.  Note that libmalloc is a much more stringent
about misuse of memory than libc.

Also, whenever possible try to hide Popup menus via XtPopdown(),
rather than creating and destroying them each time they are used.
This may be obvious.

Hope that helps.
