OK I will have a look. Is there any way to determine if font loading
is causing significant delay? And would that be an issue on
subsequent to the first frame on a display?

OK, another good pointer.
Did you have any ideas on my other email, and the finding that the
30-60 sec of lossage I am seeing when dragging one emacs frame over

Have to see if I can trace the xevents and find anything interesting..
