php

I have a website with Wordpress and PHPBB integrated - and it's been fine for months.. then all of a sudden, it's unbelievably slow to load.

There are no errors in the apache logs, but looking at the page in firebug shows a 20 second pause, before the page is delivered.

more confusing, on the same server, same apache installation, PHPBB loads in 30ms, no delay.

I tried the hogdetector wordpress plugin, which indicates that the delay is before the header is sent - which seems to agree with firebug.

Any ideas how to troubleshoot this one further?
