I'm wondering if it would be beneficial to hire on the folks who run the MySQL Performance Blog in order to squeeze every possible inch of performance out of WP.
In my experience, WP runs great when there are a few posts, however, if a company attempts to use WP as a CMS, and has thousands of pages imported as thousands of individual blog posts, then WP takes a nose dive in terms of speed and performance.
In Feb. 2007, a vbulletin forum admin enlisted their services, and had positive results which s/he shared with the larger community. His/Her thread can be found here.
I'm wondering if someone on the WP team, or even a WP blog admin, has also enlisted their services. What were the results?
