How to optimise your WordPress database


As your WordPress site grows, your database accumulates various data, including post revisions, auto drafts, trashed items, and more, which can slow down your site. To maintain optimal performance, it’s essential to regularly clean and Optimise your database. We recommend using the LiteSpeed Database Optimiser, a part of the LiteSpeed Cache plugin. Before you start, ensure you have a backup of your site in case of any issues. Here’s how to Optimise your WordPress database:
