Help! Would you recommend running ltsp on Ubuntu 8.04 or 8.10?

[Jordan Erickson]

Hey John,

I run 8.04.2 (i386) on servers with half as much ram as yours, and 
haven't had any showstopping issues like what you're describing. I ran 
into issues with the 64-bit server, but that was back in the Edgy/Fiesty 
days, and I'm sure most of them have been fixed by now. It was also not 
performance related.

Is your server NIC recognized at its full capacity (hopefully 
1Gbit/sec)? Use 'ethtool' to find out. You're using the -server kernel 
right? Also, let us know about any customizations, including nbd swap, 
any lts.conf parms, etc.


Cheers,
Jordan/Lns
