That is the client must ask for an update, then the server will send it. On a slow link the client asks for less refreshes. TightVNC over a 56k link in 8 bit with JPEG compression turned to full is definitely very usable. The latency is noticable though. (300-400ms for you to see your response to your keystroke). Over 64K ISDN things improve greatly (its the latency thats the issue here, not really the bandwidth) One thing I have noticed is the Windows VNC viewer is *crap*. During refreshes it will consume 100% CPU. Take two systems that are identical. On one put linux with a vncviewer. On the other put windows with a VNC viewer. Put them both on 100 Megabit ethernet. Load a programme that changes the screen at 60fps. On the linux client you will get close to 60fps updates. On the windows client you will be lucky to get 5fps. This is definitely due to bad coding in the Windows client. There is no reason why the windows client is so slow, other than its badly programmed. Kind Regards Crispin Wellington
