My WordPress 1.5 installation is performing very slow at the moment. Since the May 1st CSS Reboot I've had a 400 % increase in visitors (from ~100 to ~500 / day), and now it takes approx. 16 seconds to load a page.
I've done a bit of troubleshooting, and narrowed the problem down to the WordPress loop because:
- everything outside the loop performs as usual.
- the problem is the same with all themes, not just my redesign.
Right now I try to control the situation with cached pages, but I would like a more permanent solution. Any ideas?
