Putting the below in /etc/sysctl.conf both client and server machine, helped me a whole lot. I was seeing a lot of hesitations and heavy memory _and_ swap usage on the server, especially after time idle, as well as overall desktop latency and audio breakup; these knocked it all out. 2G RAM on 1GHz single-CPU old laptop client, 4G on quad-2.6GHz AMD X2 server.
That sure sounds interesting, do you think you could write a little explanation next to each parameter explaining what it does and why it speeds up X2Go, so we don't end up cargo culting?
