How to limit or disable post revisions in WordPress?

WordPress has autosave feature which creates a post revision for every minute while you edit a post. So, if you take more time to write/edit a post, more post revisions will be created in the database which may slow down your site speed. Website speed is an important factor for Google ranking, optimizing post revisions can add an advantage in improving your site loading speed.

Post revisions are good in case if you lost the connection to a post and want to reedit the post later. WordPress allows you to disable/limit or change autosave interval of post revisions to optimize your site’s database.

You can disable or limit post revisions using WP_POST_REVISIONS parameter in wp-config.php file.

Add above lines BEFORE /* That’s all, stop editing! Happy blogging. */ in wp-config.php file.
