Lately we're doing about 650,000 hits per day.... excluding images, which I don't log. So, that includes pages and protocol hits. That's 7.5 hits/second ... but in reality that means 15-20 hits/second during peak times, and less at night.
Also, remember that these are all dynamic pages ... and nearly always hitting the database.
Does this suck? Should we be able to do more than 20 hits/second on these two servers?
