Create new post on my WP 2.5 powered site loads very slow - takes about 5-6 seconds to load.
This is my server specs:
C2D 2.20 GHz
PHP 5.2.5 / XCache 1.2.2
When loading the page the CPU does not spike at all so like I said, this seems to be a JS issue. I can reproduce the slow loading in both IE8 (IE7 emulated) and Firefox 3.0 beta 4.
EDIT: It's worth pointing out that Chris Johnston's WP 2.6 demo does not suffer from this problem...
