Interesting.  For me, (on Windows) it was just the opposite.  Version 3.3.3 was medium 
slow
and I'm finding 3.3.7 to be pretty snappy, even fast at times.

Subject: 3.3.7 Xvnc MUCH SLOWER than 3.3.3 (SPARC/Solaris 7)


VNC is great technology I've used over 3 years, so I was very surprised to discover 
that dropping in Xvnc 3.3.7 to replace 3.3.3 resulted in a major increase in latency 
to move windows (in outline mode).  My client is Win2000 using the 3.3.7 viewer.  
Whereas the 3.3.3 server lets me drag windows with near-local speed following the 
mouse, 3.3.7 refreshes the outline about 5 times slower.  My Xvnc command line 
(started via dtlogin) is:
/usr/local/bin/Xvnc :1 -rfbauth /home/timwood/.vnc/passwd -alwaysshared -cc 3 -depth 8 
-geometry 1280x1024 -auth /var/dt/A:1-8QaOFT

The only change is the Xvnc version and I get the performance hit.  Fiddling the 
client connection options resulted in no change or slower still (CopyRect on).

Also, I notice that the Windows VNC service sets my local desktop background to blue 
(I'm aware of the option) and does not restore it when the client disconnects or when 
the service is stopped.

Ideas, clues welcome...
Thanks,
TW
