I enabled the Hyper Cache plugin for WordPress last week. I hadn’t had a problem with the performance of my blog but being the geek that I am tweaking every ounce of speed out if it is always on the menu.
I need to make one tweak to my blog’s theme so that the banner image is loaded through AJAX. Right now the randomness is defined in PHP, which means it gets cached along with the rest of the page… Not a huge deal, but not ideal.
In any case, Hyper Cache was the simplest caching plugin I’ve seen for WordPress and it obviously does its job incredibly well.
