I have two WP subdirectories off of a Joomla domain. The Joomla load time is ok. However, the WPs are so so sooooo slow. The back end is slow too. I have w3 cache installed on both and I've copied the settings from some great resources, but they are still slow! Could someone please take a look?
your site is calling same file two times.
