> is it better to run five children with 20 connections each, or 20 children with five connections each?
Pretty much answered in my following mail. In general each child might us 30-60mb under NORMAL circumstances, so the amount of memory on your machine will determine the upper limit for number of children. In most cases you shouldn't really need less than about 20 connections (mails processed before dying) per child. If you do it may be a sign of other configuration problems in the system, such as not limiting the size of large mails going through SA.
