It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress. ![](https://ps.w.org/debug-bar-slow-actions/assets/icon-256x256.png?rev=981156) # Debug Bar Slow Actions By [Konstantin Kovshenin](https://profiles.wordpress.org/kovshenin/) [Download](https://downloads.wordpress.org/plugin/debug-bar-slow-actions.0.8.4.zip) * [Details](https://wordpress.org/plugins/debug-bar-slow-actions/#description) * [Reviews](https://wordpress.org/plugins/debug-bar-slow-actions/#reviews) * [Development](https://wordpress.org/plugins/debug-bar-slow-actions/#developers) [Support](https://wordpress.org/support/plugin/debug-bar-slow-actions/) ## Description This plugin lists the top 100 slowest actions and filters during a page request in WordPress. It helps you figure out performance bottlenecks in themes and plugins. Requires [Debug Bar](https://wordpress.org/plugins/debug-bar/). Current limitations: * Does not time nested actions and filters due to a core bug * Does not time actions and filters before plugins_loaded or muplugins_loaded if placed in mu-plugins * Does not time actions and callbacks after wp_footer at priority 1000 ## Screenshots * [[ * Screenshot ## Reviews ![](https://secure.gravatar.com/avatar/b5c3820a86f5117c5e2bdb962af4b189daf0b104f9ddf94012400cf62c6e63b1? s=60&d=retro&r=g) ### 󠀁[Useful!](https://wordpress.org/support/topic/useful-973/)󠁿 [Jonathan Pasquier](https://profiles.wordpress.org/jpasquier/) April 14, 2023 Some code was slowing my site, and I was unable to pinpoint the culprit with other tools such as Query Monitor. Thanks to this extension I have been able to identify the problem and solve it. Plugins works well with WP 6.1 Thanks! ![](https://secure.gravatar.com/avatar/d49b2c85288e7564c2d8c4d32130da731b9f949777fecb096c351303d19a4dbb? s=60&d=retro&r=g) ### 󠀁[Indispensable!](https://wordpress.org/support/topic/indispensable-220/)󠁿 [Gemini Labs](https://profiles.wordpress.org/geminilabs/) February 22, 2022 This plugin is essential for plugin development! It also works with the Query Monitor plugin. ![](https://secure.gravatar.com/avatar/8ac11b2c7f5edabfaeaf13306a89a343ee0c9469e0eaf3f35a1346c40635596b? s=60&d=retro&r=g) ### 󠀁[Very helpful (in 2021 as well)](https://wordpress.org/support/topic/very-helpful-in-2021-a-well/)󠁿 [iwanwilaga](https://profiles.wordpress.org/iwanwilaga/) August 14, 2021 It was THE tool that finally helped me to spot the function (action) that made the pageload slow. I failed to do the same with Query Monitor, Debug This, F12, P3.. and other plugins. I don’t know many other plugins that can do exactly this. Probably New Relic? But that has a complicated and deeper-level install process. Plus not open source.. So, thank you.. and please keep taking care of this and maintain sometimes. A useful treasure for humankind! 😉 Best wishes, Wiktor ![](https://secure.gravatar.com/avatar/c73aebb1d4d2f1b212c6244b364a99ace9c7ee8da1d94111bbaca3eaedf71917? s=60&d=retro&r=g) ### 󠀁[Great!](https://wordpress.org/support/topic/great-8542/)󠁿 [wpcraft](https://profiles.wordpress.org/casepress/) September 17, 2018 Very simple and usefule.

It helped me to discover why my admin pages were taking 10.5 seconds to load. The plugin showed me that the action “admin_menu” was taking 10.5 seconds to be executed. Investigating all occurences of the string “admin_menu” in my theme code, I found an external request to a web site which is not on-line anymore and, cancelling it, my pages now load in 1.5 seconds.
