The Condor Manual says in 126.96.36.199
"Also consider network traffic and your network layout when choosing your
central manager. All the daemons send updates (by default, every 5 minutes)
to this machine. Memory requirements for the central manager differ by the
number of machines in the pool. A pool with up to about 100 machines will
require approximately 25 Mbytes of memory for the central manager's tasks. A
pool with about 1000 machines will require approximately 100 Mbytes of
memory for the central manager's tasks. A faster CPU will improve the time
to do matchmaking."
