[X2Go-User] Speed and responsiveness increase

[Jonathan Brickman]

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.
