Hi,
We upgraded from 3.7.1p2 to 3.9p1. The behaviour of the X11 forwarding
changed significantly, it is much slower. See below the truss output
(server side which runs 3.7.1p2) an check for the timestamp (6 seconds
delay). Do you have any idea what may causes this behaviour? Platform is
Solaris 5.9 Generic_117171-05.
Thanks in advance,
Andy Kocher
