After installing UBUNTU 12.04 (TightVNC Viewer version 1.3.9) I noticed that vnc is really slow (latency) even though I have a gigabyte network Ethernet connection. I'm running TightVNC Viewer version 1.3.9 with the minimum graphics settings and its still horrible. I also notice that the linux arp command takes a little longer to respond then it did before when I was running 10.04

Does switching to 100 megabits with ethtool (or an old router) help? 1000baseT can be slower than 100baseT for chatty things like scp, http://fixunix.com/ssh/368694-scp-unbelievably-slow.html maybe the same is true with vnc.

(Also, you mean 'gigabit', not 'gigabyte'.)
