[mohaa] curious behavior

[Mike Mabe]

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?
