If you have a smaller database or have been experiencing database performance issues, disabling post revisions might be helpful for you.
To disable post revisions, open up the wp-config.php file, and add the following code -
define('AUTOSAVE_INTERVAL', 300 ); // seconds
define('WP_POST_REVISIONS', false );
This will disable post revisions, and increase the autosave interval from 1 minute to 5 minutes.
