They give you baseline numbers to compare with other baseline numbers, but only for your server, not your actual site. For years now I've wanted to write a programlet that would take actual logs from my sites and play them back with a curve of multiples, probably across several clients, logging response times across the curve. Seems simple enough if I'd make the time. Like everything else simple it's probably been done already. Several times. Has anyone seen a tool capable of this kind of "replay" testing?
