Find Slow Functions & Actions & Filters & Hooks (Debug Bar)


[ ✅ 𝐒𝐄𝐂𝐔𝐑𝐄 𝐏𝐋𝐔𝐆𝐈𝐍𝐒 b𝓎 𝒫𝓊𝓋𝑜𝓍] :

• Revised for security to be reliable and free of vulnerability holes.
• Efficient, not to add any extra load/slowness to site.
• Don’t collect private data.

Plugin Description

Find out slow functions, actions or filters with their exact times in seconds or milliseconds.


Note: Plugin is experimental and we take no responsibility. However, practically there shouldn’t be theoretical case when this plugin can break/mess-up the site. The only possible gotchas are:
* This tool depends on WordPress internal functions and one day this plugin might become misfunctional (we can’t rpedict that).
* This plugin automatically&temporarily sets needed variables in several WordPress files (wp-config.php & class-wp-hooks.php), so whenever (if) this plugin cause error in website, deactivate & uninstall plugin, and remove the “added parts” from wp-config.php and retract back the last wp-includes/class-wp-hooks.php__DFTwp_BACKUP file. That should be all.

Available Options

Considerably slows down the website and provides unreliable data.

This plugin works .. but it's ugly, and doesn't follow any of the style conventions used and familiar to WordPress.
