Hook Timer attaches to the start and end of each action and filter, stores the timestamp, and when the hook finishes, logs the total time spent. If you want to examine why a page is slow or aren’t sure where the majority of your page load time is spent, this plugin will show you the most costly hooks in your installation.
Hook Timer appears as a menu option in your admin dashboard, and displays the total time spent in each hook on the previous page load. This allows you to load a particular page that’s slow, then to view the results in the admin dashboard immediately after.

Hook Timer
