Hi Achim,
if you use X2Go Client 4.0.1.5 and above this performance issue should
be solved.

Package: x2goclient
Version: 4.0.1.3-0~522~ubuntu14.04.1
When I connect from Kubuntu 14.04 to a server, also running 14.04, x2goclient
consumes without a proxy 200 % CPU, with a proxy connection almost 300 % CPU.
(same with pkg 4.0.1.1-1 from ubuntu archives)
I tried to connect to the same server via a Apple Laptop using the 4.0.1.3
x2goclient and it uses only a few % of the much slower CPU.
I asked a coworker running Kubuntu 12.04 to connecting to the same server and
his client only generates 3-5% CPU load.
A few weeks ago when I last used x2goclient the laptop fan didn't produce any
noice, so I assume the problem is a new one in Ubuntu 14.04.
x2goclient shows in GUI:

To me vi is Zen. To use vi is to practice zen. Every command is
a koan. Profound to the user, unintelligible to the uninitiated.
You discover truth everytime you use it.
