We do have a (virtual) 10Gig, 6core machine for x2go with 6 users. Some
x2go-agents become really big memory-wise. And all the browsers consume
gobs of memory.

And I haven't yet determined if the latency of x2go, the latency of
the home-dirs via nfs or the latency of the os-disk via nfs is the most
significant factor that users are kind of dissatisfied:-(

Probably the added latency of the network-connections between disk-less
clients and server and between the server and its disks. I hope
reducing the later improves things a bit.

Anyway, x2go did actually help us solve some problems and proved to be
a better and more stable environment than the vnc-based solution we had
before.

Have fun,

Arnold
