Re: [Ltsp-discuss] Local apps

[Daniel R. <daniel.ramaley@DRAKE.EDU>]

DNS_SERVER is set, and it shows up in resolv.conf. nslookup works fine. 
I don't think DNS is the problem.

The machine has 64 MB of RAM. I've also set it up with 64 MB NFS swap. 
But even with Firefox loaded, the swap isn't touched (according to 
/proc/meminfo) and there is still nearly 2 MB free RAM. So it isn't 
running out of memory. Previously i was using LTSP 3.0 with X, Black 
Box, and Netscape 4.x locally. It loaded quickly. But LTSP 4.1 with X, 
Black Box, and Firefox takes many minutes to load. Does Firefox just 
use that much more CPU than Netscape? I almost wonder if there isn't an 
nfs problem that is causing it to load so slowly, but i don't know 
where to start to determine whether that is the case.
