The only figures I can contribute is that FOR ME the postfix "local"
service is about three times as fast if it's NOT using procmail (c. 11
vs c. 3,5 mails per second) for local delivery. However, the
administrator efficiency greatly increases by switching to Postfix since
it's easier (than sendmail and qmail) to setup, debug and maintain.

This is for an otherwise unloaded PC (K6-2/300, 1 MB 100 MHz L2, 128 MB
SDRAM, 5400/min Western Digital AC420400D (1966 kB Cache), VIA MVP3 chip
set using UDMA/33) running Linux 2.2.14 on ext2fs sync spool and vanilla
ext2fs home directory. All partitions without sparse_super and filetype
flag.
