[FreeNX-kNX] FreeNX performance

[Edilmar]

Hi,

I have installed NX (from NOMACHINE) + FreeNX into my Fedora Core 2 
system,using the tutorial in 
http://fedoranews.org/contributors/rick_stout/freenx/. Then, I have
started the NX Client to connect to server. All works, but no too fine
in performance,this is like VNC speed, more and less. Is there something 
I need to do to connect faster? I tried to connect using LAN and WAN. At 
LAN, VNC is faster, and at WAN the performance is more and less the 
same. What's the problem?
