Hi Bill,
the delay is due to all the X11 messages sent between app and X server.
We already greatly reduced the startup time by delaying as much as possible
the initialization of X resources, like fonts and colors (especially on
true color and direct color devices). To improve things more one can think of
a higher level protocol than X11 (an initial attempt was made in the
TGXServer and TGXClient classes, but quite some work remains to be done to
make it fully functional). Another approach is to not use X11 over WAN but
make a simple event server (maybe just accessing remote event files via
rootd is enough) and a local event display (like one would have to do in
a Windows environment anyway).
Cheers, Fons.
