Run iptraf or ibmonitor to see actual network bandwidth being used. I
personally feel 100mbps is sufficient as for days at end max bandwidth
reported in systems is no more than 7~8mbps!!! These are serving ~25
clients each.

Check with top what amount of processing / memory is tuxtype or
tuxpaint taking. If that is he bottle neck then you may want to set up
different nice values. I reported this on LTSP list that chess
(gnuchess as well as xchess) took up huge amount of RAM and processor
time.
