I guess you could use 'top' in a unix window.
Then kick off 1 drone only and look at the memory usage. Then * it by the
number of processes you expect.
55 is a lot of processes!!!! On Any unix system.
Perhaps you could stagger the number of processes. so maybe spawn 30 drones
and have each drone process 2 sites in serial, one after the other?
I've seen some pretty large perl processes on very simillar spec machines as
yours.
