[wp-hackers] Incredibly High PHP Creation Times on WP SVN?

[Computer Guru]

I'm having this really weird issue with WP SVN, wondering if anyone can point me in the right direction...

On my blog (http://neosmart.net/blog/) I'm experiencing really (really!) high PHP page creation times, on "stock" configuration:

I tried to disable all plugins and turning off object caching, but it makes *zero* difference. No other script on my site suffers from the same problem (vBulletin, Gallery2, and more).

I've tried both Apache 2.2.6 and IIS (6 on Windows 2003) w/ FastCGI and *SAPI to no avail. Even with an awesome opcode cacher (XCache), I'm only getting anywhere from 3-50 second page generation times. I installed the MySQL inspection plugin - MySQL queries take .0x seconds *maximum* and the rest is all PHP. I tried PHP 5.2.3 and PHP 5.2.4, no difference. Tried threadsafe and non-threadsafe binaries, no difference.

It doesn't seem to be a server configuration issue since it works brilliantly for everything else and occurs on both IIS and Apache on two different versions of PHP.

Does anyone have any idea if any changes in the WP SVN code recently (last 2 - 3 weeks) could result in this bizarre behavior?

Microtime stats are displayed in the footer, you can compare them to those on vBulletin @ http://neosmart.net/vBulletin/ in the footer as well.

How do I go about seeing what's causing these exorbitant page creation times?
