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.

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

This is the perfect add-on for the "Debug Bar" plugin. 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.
