This is a good idea (distributed benchmarking), but we didn't get it to work as advertised. Overall disappointing - maybe revisit when it matures.
===[http://github.com/oremj/logreplay log_replay]===This is a perl python script that oremj wrote. Given a log, it will replay the hits. This gives you the advantage of replaying an actual set of hits across multiple pages, giving you a good distribution of hits. This is mostly useful if you have actually had people using the site.
