Plugin Profiler

LICENSE TYPE: INFINITE

Description

Basic profiler for WordPress Plugins. Benchmarks any given plugin by testing response times with and without the plugin activated.

Plugin Profiler is on GitHub.

Bug reports (and pull requests) are welcomed on the Plugin Profiler GitHub repository.

Please note that GitHub is not a support forum.

Profiling a plugin

This plugin measures response times of any URL on your website in the following ways.

No plugins activated
Only the selected plugin(s) activated
All but the selected plugin(s) activated
All plugins activated

It then plots the response times in a chart and calculates the average response time time difference.

While this way of profiling a plugin is very low-tech it can be interesting to measure the impact of a plugin on your sites response time.
Please note that this way of benchmarking leaves a lot of factors out like additional HTTP requests caused by a plugin, etc..

Installing Plugin Profiler

Since this plugin needs to filter out which plugins are activated for the profiling requests, it needs to be installed as a must-use plugin so its loaded early.

Have a look at the installation instructions for details.
