On a hunch try fewer prespawns (to keep them from robbing each other
of processor time needlessly since IO accounts for a very small part
of a typical spamd run) and try far fewer connections per child say
15 or 20. Then start tuning for your particular load.
Of course, I've been known to be all wet before. This is particularly
common with me in an insomniac state as I am now.
