# If you are running on a small system with limited
RAM, you should
# note that each child takes just over 20MB.
#
# As a rough guide, try 5 children per CPU. But read
the notes above.
Max Children = 5

an average message

Compaq DL360 G1. Dual Pentium III 1.26GHz, with over a
gig of memory.  Plenty for the job.
