When you activate or deactivate a plugin, it measures the memory usage. The difference between these measurements gives an estimate of each plugin’s memory impact. These measurements are estimates and may vary. Factors like caching, other active plugins, and WordPress itself can influence memory usage. This plugin also show the current memory usage of your wordpress site. If you use more than 80% of memory limit this plugin gives you the option to increase the memory limit, while providing comprehensive **system monitoring** and **version checking** capabilities for both PHP and MySQL. ### Key Features * Monitors and displays memory usage for individual plugins * Shows memory usage history for each plugin * Calculates average memory usage based on historical data * Detects when memory usage exceeds 80% of the allocated limit * Provides an option to increase the memory limit when high usage is detected * Displays current memory usage percentage in the WordPress admin bar for quick reference * Optimizing Memory Usage for Better Performance **Memory Management Features:** – Monitors and tracks **plugin memory usage** – Detects high memory consumption and offers **memory limit increases** – Provides memory usage history and performance analytics – Shows current **WordPress memory usage** with visual indicators **Performance & Security Benefits:** – Identifies **memory-hungry plugins** affecting site performance – Monitors **server compatibility** and **system requirements**– Helps maintain **WordPress security** by alerting to unsupported software versions– Prevents **compatibility issues** before they impact your website – Supports both** MySQL** and **MariaDB** database systems alerts ### Why Use Plugin-Memory-Usage?

My WordPress site was using way too much memory and I found out which plugin it was. Envo Extra. It was using 26 MB of memory. That is pretty high when the normal Wordpress limit is 40 MB. No problem, Plugin Memory Usage has a button you can click if the system are using over 80% and then the limit is increased.So, all in all, great plugin I would recommend this to others, and its 100% free.
