Here is an example from a server that has constantly over 500 concurrent smtp connections to spamd and takes more than 1.000.000 connections a day. spamdb | wc -l && ls -lah /var/db/spamd 251365 -rw-r--r-- 1 _spamd _spamd 88.3M Jan 24 15:07 /var/db/spamd As you can see the size of the database is quite ludicrous. You should just take care that for this kind of size, you will have to raise max table-entries in pf.conf. As for the CPU usage, spamd on this machine uses 10% at max of one of the CPUs (2X Intel(R) Xeon(R) CPU 5130 @ 2.00GHz), and is generally at 5% or less.
