So > I'd wager ~1800 messages per hour or 43200 messages a day. Mail load isn't distributed evenly over the course of a day. From my ISP days, peak was 9am to 3pm for a userbase largely clustered around our home TZ. For a more distributed user population, that's going to vary a bit. As much as 80% of the mail would be arriving during this four hour period -- or 1/6 day. That's about 5,760 messages/hour (assuming I can read and do math, which may be a stretch). So your 1800 messages/hr would be lagging by 3 hours per hour of runtime. Disabling network tests increases throughput markedly. I've been looking for some performance statistics but can't find anything through Google. Note to that spamd is a true network-accessible daemon and can be accessed round-robin style for distributed spam-processing. Peace. -- Karsten M.
