server

As I mentioned in my previous post, the site was bottlenecked by having the Apache/PHP and MySQL servers on two separate machines. This is the standard setup at Dreamhost; even if you have a PS, the mysql part is hosted on a different server. So even if you don't have to share a machine with other websites hosted on Dreamhost, you're still sharing their network latency when the Apache/PHP server is communicating with the MySQL server. On a typical non-cached page, the IVRPA site makes 200-400 queries to the database.
