Improve Vine server performance


We are using Ultravnc server on Windows OS and are currently evaluating Vine server for Mac OSX. While comparing Ultravnc and Vine OSX performance with same configuration, we find ultravnc to be marginally better and when ultravnc driver is enabled, its more than twice faster.

I have read the FAQ, which talks a bit about performance & extensively searched on Internet, but couldn’t find something magical. What more can we do to get better performance or frames/seconds from Vine and is there a driver available like one for ultravnc on Windows?

We have made comparison at following configuration: Encoding:Tight, Zlib:5, JPEG:7, Color depth:16/24 bit, resolution:1024x768, latency:1ms; OS:snow leopard/Lion


Anyone, any help or suggestions?
