James,
When I posed this question to my Network Admin, he installed a traffic
logging tool to monitor traffic. Network traffic peaks of 60% were not
uncommon while VNC'ing into the machine, but average traffic was under 5%.
CPU Usage history, however, shows average utilization above 25% and peaks
at 100% that last for several seconds.
This appears to be a CPU performance issue. The system is capable of
dual-processors, I think I'll drop a second one in.
Thanks for your help, and helping me do a reality-check!

AM ethernet port?
Brian,
Unless the polling application running on the machine is very aggressive,
I'm surprised that it affects VNC in the way you describe - are you sure
the
problem isn't to do with update capture performance or CPU load rather than
network throughput?
You could download a free trial of VNC Enterprise or Personal Edition from
http://www.realvnc.com/download.html, which give better performance than
the
current Free Edition release, including making use of a mirror video
driver.
You can safely upgrade to that, give it a try & downgrade to the Free
Edition if need be (although you may need to re-configure the Free Edition
server afterwards).
Hope that helps,
