One thing you might want to try is to use /dev/urandom instead of
/dev/random for SASL on your system (recent versions have a
--with-devrandom configure switch, otherwise you need to edit config.h).

Additionally, you may want to increase the number of preforked processes,
but this will only allow you to prevent larger spikes of activity from
affecting you adversely, it won't help if the load is sustained at a
higher level.
