I've just upgraded from 1.2 to 1.3, and there is a noticeable slow down in things. My index.php contains roughly 100 queries (lots of stuff), and the page :
- used to render in 0.5 seconds with WP 1.2
- renders now in 1.5 seconds with 1.3 alpha 5
(steady benchmarks, it's almost millisecond acurate)
Any clue why it slowed down ? Anything not that compulsory that can be turned off in the engine ?
