Well, first guess is that you have a large, colored display (nice picture of the kids in the background?) and use a high compression rate in the vncserver. That does take a lot of cpu to compress the screen to send to the client. Some things to improve performance, in random order: Use a smaler screen size: a 1600x1200 screen is 4 times as much as a 800x600 screen, all data that needs ot be processed by the vncserver. Use a lower colordepth. 8 bits colors (256 colors) is the optimum for vnc. 16 bits (65000 colors) does take twice as much. 24 bits (true color) takes 3 times more than 8 bits. 32 bits (true color) takes 4 times more than 8 bits. all because it is that much more data. Use as much flat colors and square windows as possible: no gradient fills, no pictures in the background (not even a raster!) no rounded corners (use clasic window decorations). Some vncservers can/do remove the background picture once a connection is made. Remove as much update-handling as possible. The ultimate is to 'poll on event received only' and 'poll window onder cursor'. Use no compression at the server side (this needs a high bandwidth network). Optionally twiggle with the compression types to see which one suits your needs.
