Really, it's more the fact that the image is sent back to the client from the server with XGetImage(). That means marshalling from device pixels to 24-bit RGB and sending that over the wire to the client (possibly shm on the same machine, but still, IPC). The performance suckiness of such a scheme is why things like XDamage and XVnc exist. ;-) -- muppet <scott at asofyet dot org> _______________________________________________ gtk-perl-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtk-perl-list
