It’s a good idea to limit the number of post revisions as they consume unnecessary space in your WordPress database. Searches by plugins may also include post revisions unnecessarily, affecting the performance of your site. To limit the number of revisions, all you need to do is add this line in your wpconfig.php file
define ( ‘WP_POST_REVISIONS’, 3 );
Once you add this line, WordPress will save only the last 3 versions of your posts and discard the previous ones.
