Note that Dreamhost recently moved from using mod_php to running PHP as a FastCGI server (per website/account).

So I assume PHP no longer has the performance advantage of integrating closely with Apache.

In fact, since Dreamhost now offers Passenger (AKA mod_rails) as a solution for running Rails and Django) PHP might be at a disadvantage. Especially when paired with a large framework (zend,codeigniter,cake, etc.)
