Both on the same box, with some level of spam filtering too - using DNSBLs (light load) and Spam Assassin (tagging only). I had to update from a 486 to handle body tagging. Spam Assassin is /bin/sh based so was killing the machine. Perl based filtering agents have the same (or worse) problem. The startup load for a dozen parallel perl proceses can quickly kill a ramstarved (< 256Mb) machine. Memory is more important than CPU most of the time - if you start hitting swap, you're only going to run as fast as your hard drives, even if you have a 200GHz Itanium processor from5 years in the future.
