F12-Profiler

Description

This plugin will track the load time of each plugin, javascript and css file
to help you optimizing the performance of your WordPress site. It will help you
to figure out which plugin / resource causing the slowness of your page.

Track time for:

1. Core
2. Theme
3. Plugins
4. Resources (JavaScript, CSS)
5. External files

Installation

1. Upload the plugin to the “/wp-content/plugins/” directory.
2. Activate the plugin through the “Plugins” menu in WordPress.
3. Activate the plugin itself in “Tools” -> “F12 Profiler”.

Important: The plugin will not track anything before activated by yourself (see the steps above). This will allow you
to disable the plugin within the options without uninstall and install it all the time if you require it.
Also, it will only be activated for logged in users that are able to manage options of plugins.

If you have any further questions do not hesitate to ask.

Don’t use P3 use F12-Profiler!

Doesn’t do anything

Installed the plugin, nothing happens. No link in the admin bar, nothing in the admin menu, no new settings. Wasted my time.

partially useful

Plugin is working and I see some stats. However I have a certain plugin that’s delaying all the pages with more than 10 seconds and there is no mention of it in the stats, everything looks fine there, but it’s not.

Excellent work!

Great details. The only thing causing me to rate it as 4 stars and not 5 stars is missing a way to save the results to file. Add this and I’ll change it to 5. Promise!

Finally an alternative to P3

Excellent! After P3 doesn’t work with PHP7+ anymore, F12 seems finally the one stepping in to fill that gap. Update [18-Jun-19]. After some small contributions of mine to the dev efforts, the plugin developer has decided to add me to the team, long after this review was written.
