[mohaa] recommended settings for server?

[Troy Chinnery]

The kernel probably won't let it grab more than 80% because 20% is being used 
by other processes. You can have more predictable memory usage by using the 
com_hunkMegs and com_zoneMegs variables on the command line. Values like 
hunk=128 and zone=48 are common but for newer games often larger. With only 
128MB of memory, try hunk=96 zone=24. This will minimise swapping BUT there 
may be some levels your server won't load and/or might not handle 32 players.
