[mohaa] curious behavior

[Charles "BedMan" Bedford]

Hmmm...  I rather doubt it.  The lag is most likely due to lack of cpu
power.  What kind of system loads are you sustaining on the server?  If they
are relatively high, then it's probably a cpu bottleneck.  If they are low,
it could be a network bottleneck.  There's a lot of traffic that goes to a
large server, and the TCP/IP stack can take a lot of heat for it.

here is a question a little off the topic but you seem like you might know.
I have a server running several game engines but the 20 man seems to lag and
not any of the others. It's a dual and cpu according to top is about 40% on
both cpus. would setting the nice level for that particular engine help the
lag at all?
