WP Plugin Profiler – Find Out Which Plugins Are Causing Performance Issues in WordPress

WordPress can be fastest if managed properly but most beginners start with plugins which make life easier using WordPress not knowing the impact of such plugins on the performance ending up with a very high unstable configuration hitting the high loads on server and receiving emails from hosts suggesting switching over to higher plans for better managing the load.To take such a decision it is important to first identify what’s causing such a load on the server, if its just traffic ( which is very good ) or if the load spikes are without traffic then the cause could be something else which needs to be examined.WordPress Plugin Profiler

To identify whats causing the problem you need to install another plugin called P3 (Plugin Performance Profiler) which tracks the performance of all the installed and active plugins on the server.Its very easy to use, just Upload, Install and Activate the plugin.

Here are steps to do a test, for assessing the performance bottle necks in your WordPress Setup :

  • After activation Go to the Plugins Settings Page which can be found under plugin under Tools –> P3 Plugin Profiler.
  • Click the “ Start Scan ” button  which should open the Performance Scan Window – from which the scanner will analyze the speed and resource usage of all active plugins on your website as various page are opened and as links are clicked in the blog.A Tip : try opening up different types of links like Post Pages, Category Pages, Archives, etc., so that there are various instances of different plugins running in the background which can make it a comprehensive report as to how much resources/time various plugins are taking.
  • The scan be either Automatic or Manual.In the automatic mode the scanner generates some traffic on your site, monitors your site’s performance on the server, and in  a Manual Mode the user needs to click links for tracking the performance.
  • Once you have done navigating links from the performance window, Click the “ I’am Done ” button on the bottom right which should stop the test and the report get generated similar to the image below.
