Index WP Users For Speed is a WordPress plugin designed to enhance the performance of sites with a large number of registered users. By utilizing optimized MySQL and MariaDB techniques, this tool significantly reduces the loading times for users, posts, and pages within the WordPress dashboard. It effectively restores functionalities that recent WordPress versions suppressed, such as changing authors in the Gutenberg editor and displaying user counts, ensuring a smoother experience for site administrators.

The plugin works by indexing users and adding easily optimized metadata, which prevents the need for slow full table scans during database queries. Additionally, it allows for background updates of metadata indexes, which can be scheduled during off-peak hours to minimize impact on site performance. While it can be used independently, it functions best alongside the Index WP MySQL for Speed plugin, making it a valuable addition for those looking to enhance their WordPress site's efficiency.
