Display memory, page load time, average load time and query count in the footer of your site.
Testing your WordPress site? This plugin allows you to display memory, page load time and query count in the footer of your site on both the front-end and within admin.
This plugin is partly based upon the WP Query Counter by Steven Word (http://www.stevenword.com/plugins/wp-query-counter/) and has been customised for my testing needs.
If you'd like to contribute to the plugin you can find it on GitHub: https://github.com/mikejolley/WP-Page-Load-Stats
