Hmm, I’m still having this problem with a pretty much standard WordPress 2.1.2 one-click installation on Dreamhost (only added the K2 theme). I checked the ‘wp-cache-phase2.php’ file, and found no ‘ob_end_clean()’ but only ‘ob_end_flush()’ in the 2.1.2 code.
WordPress is really slow the first time I try to load my site. I tested with iwebtool and got these load time results from three sites of mine, all on the same Dreamhost hardware: WordPress 75,61 seconds, Drupal 0.92 seconds, Joomla 2.03 seconds. The next time around (a few seconds later), the results were WordPress 0.53 seconds, Drupal 1.22 seconds, Joomla 3.56 seconds.
Not being an expert at all, it seems to be a cache generation issue of some sort. Every WordPress page will take ages to load on my site, where after they are blazingly fast. But after a while, the load time will be 60+ seconds again..
I’m not using wp-cache at the moment, since it just seemed to make matters worse. Please help me if you can.
