Using the WordPress Query Monitor Plugin
What is Query Monitor?
The Query Monitor plugin is a free debugging tool that helps assess the performance of your website. It gives an in-depth analysis of all of the requests being made to the server including database queries, HTTP requests, hooks & actions, and so much more. It can be used to help identify a plugin, script, or database query that is negatively impacting the load time of your website.
Troubleshooting website performance issues can be tricky. If you are experiencing performance issues with your website and have already checked obvious causes, the Query Monitor plugin can help you dig deeper into the functionality of your site to identify problems.
