Did you see the follow-up message indicating that you are running the vncviewer in the wrong place? I think that explains all of the problems you were having, including why the bandwidth was being mis-detected. In fact, it wasn't being mis-detected. It's simply that you're trying to run vncviewer on the same machine as the VNC server. You need to run vncviewer on "local", not "remote". > Well there's about an order of magnitude speed difference if I don't use > -C !! That's what led me to think it was coming raw down ssh link. Since you are running vncviewer on the server, not the client, what's coming over the SSh link are XPutImage() requests, which most definitely would benefit from SSh compression (but would still be very slow compared to VNC compression.) > yes, running ssh -C , jpeg quality can be seen to change and F8 > connection information shows "requested encoding" changes according to > what I set on command line or via options dlg. Yes, because what is happening is that the VNC server (or module in this case) is compressing the images as JPEG, vncviewer (which is running on the same machine as the module) is decompressing the JPEG images and drawing them as uncompress X bitmaps. The uncompressed X stream is what you're passing through SSh. That is not what you want. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
