Comment 1 for bug 29819

I just switched to "x11vnc" to see how it compares.

It uses less than 1% of my CPU and around 5 kbytes of network traffic per second (1k upload, 4k download).

This is quite different from vino! In both cases the screen was the same - a static, full-screen Firefox with a flashing cursor and 4 small graphs in the top panel.
