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: <a href="https://github.com/mikejolley/WP-Page-Load-Stats" rel="nofollow ugc">https://github.com/mikejolley/WP-Page-Load-Stats</a>

WP Page Load Stats

Not sure why this only has 100+ users but this is a great tool!

Excellent!

Display memory, page load time, average load time and query count in the footer of your site.

Logs memory usage as users browse your website providing latest logs and flagged logs (when memory usage is over specific percentages).
For users who have specific capabilities (e.g. administrators) a memory meter is shown in the admin bar showing memory usage as the website and dashboard is navigated and includes several configuration options.

<h4>Usage</h4>
After installation memory usage will be logged for any user as they browse the website and dashboard, you can see the logs via the Memory Meter menu in the WordPress dashboard.
By default the memory meter will be shown in the admin bar if you are logged in as user with the <code>manage_options</code> capability such as an administrator (the capability can be modified if required, see the configuration tab via the Memory Meter page).
In this scenario you will see the meter in the admin bar at the top of your WordPress dashboard and the frontend of your website. Note that there is a user profile setting in WordPress to enable the admin bar, it is enabled by default, if this is not enabled you will not be able to view the memory meter in the admin bar.
If you hover over the memory meter you will see a number of options, such as logs and configuration. In addition to the admin bar, a menu item is included in your WordPress dashboard to give access to the logs, confirguration, etc.
Note that the memory meter doesn’t need to be displayed to ensure memory usage is logged, this is done regardless of whether the memory meter is being displayed.
