How to Use Query Monitor to Debug WordPress Performance

WordPress is a popular content management system, but its performance can occasionally suffer. Identifying slowdown causes is easier with tools like the Query Monitor plugin, which aids in debugging and analyzing website components. After installing and activating the plugin via the WordPress dashboard, users can access a variety of performance metrics directly from the admin bar. Query Monitor provides insights into PHP errors, database queries, hooks, and script/styles, offering detailed views such as the count and duration of database queries and PHP error warnings. It also shows how scripts and styles affect page loading times. Using this data, developers can optimize slow queries, resolve PHP errors, and improve script loading for better performance. Overall, Query Monitor serves as a comprehensive tool for enhancing WordPress site efficiency.
