This is a problem with the downloadable version, which is written for the LAMP stack and grew over something like 10 years as an open-source effort. Not surprisingly, YMMV (as with all OS software).
The hosted version (called OnRamp) would be the place to start - it's free, performs better (it's not all PHP), and gives you easy market integration (which the original comment was referring to). OpenX may or may not be what you're looking for, but at least you can test the waters without any initial investment other than creating an account and setting up a few tags.
