8.04 ltsp +slow

[Uwe Geercken]

hi and "Moin, Moin"

I am a little bit puzzled now: some documentation I found on lts.conf  
tlaks about:

USE_NBD_SWAP=Y|N

you and other sources talk about

NBD_SWAP=True|False

which one should I use in ltsp5.


also, so far my biggest problems are on the network side. what is the  
easiest way of monitoring the traffic volume on the network between  
the server and the clients? I would like to use this to determine if  
certain changes to settings are better or worst. also I could use it  
to monitor application traffic.

tks for help.

uwe
