I've been running my site (http://www.drewvogel.com) on WordPress since version May 24, 2005 on my self-hosted server (PHP 5.1.6; MySQL 5.0.27 on a Fedora Core 5 box).
Last weekend, I upgraded from 2.0.10 to 2.1.3 by deactivating all my plugins, downloading any updated versions of plugins and installing them (there were several that were for version 2.1 or later, so I installed those), deleting all the WP files from my server, and uploading the 2.1.3 files. I then re-activated my plugins (one-by-one -- WP REALLY needs a batch operation for plugins!).
My site's admin is running EXTREMELY slowly where it used to be fast... The Dashboard elements take a long time to appear, loading the WRITE or MANAGE pages takes over a minute, etc.
I wonder if it might be one of the plugins that's causing a bottleneck, but am unsure how to determine which one. Can anyone provide me with some guidance on where to look, what to check, and how to fix this issue? Thanks!
