I have a separate Linux machine with two bridged interfaces and some qdiscs to control latency and bandwidth. We've also done some tests using UMTS and DSL connections. > In the > next-gen version of TurboVNC, manually enabling the Continuous Updates > extension (which causes the TurboVNC server to send updates immediately > to the client) produces significantly better throughput on this type of > connection, but none of the TigerVNC enhancements seem to have improved > its throughput. We've been focusing on responsiveness, but that should be correlated with throughput. Example tests have been typing, dragging things around and playing movies. Note that maximum throughput has explicitly not been the goal. Doing so would have ruined latency as that fills up buffers. The goal of the algorithm is to maximize throughput without sacrificing latency. In practice it can of course never be perfect, but the numbers I've seen during my tests shows that it tends to be pretty damn close. Further improvements can probably be made, but we're at a point where we deem it good enough for now and are looking to put the stuff in the hands of users first.
