We do public opinion surveys and use VNC to monitor the surveyor to make sure their work is accurate. We had switched from M'soft SMS to VNC because SMS was way too slow. We did that several years ago when our primary application was DOS based. Now that we've upgraded to Windows software, VNC has a serious impact on the speed of the interviewing software. I've tried AT&T, Tridaic, and now TightVNC. It's not so much VNC, but the system resources diverted to VNC on the client that causes the application to bog down completely. The application uses Visual Basic. I'm sure the problem is with machine resources and not network speed, we are on a 100MB line and changing encoding/compression levels hasn't had a major impact. The machine being viewed can have as much as 50% of their processor time used by VNC. The clients are PII 450, with 128MB RAM.
Does anyone have any ideas how to negate the impact on the client machine? Is one version of VNC better at this than others? Also, for TightVNC is there a way of using command switches to turn off CopyRect encoding and make Display-View Only the default? It seems those have to be set each time.
