Thin Clients Swapping - insufficient RAM?

[RalfGesellensetter <rgx@gmx.de>]

Dear list,

while elimination server and network bottlenecks
(Gigabit Uplink, more CPU), I started wondering if
network swapping (as observed during backup) 
might be the clue - respectively too few RAM in 5-6 years 
old EPIA clients.

At http://www.ltsp.org/~sbalneav/LTSPManual.html#id2696965
I read that 128 MB RAM is recommended - does our documentation mention 
this as well?

Will try to upgrade thin clients and possibly have a look at network 
swapping configuration  (http://www.ltsp.org/twiki/bin/view/Ltsp/Swap).

Comments & hints are welcome.
Regards
Ralf
