It's a famous WordPress myth that storing multiple post revisions will slow down your website. This is not true because WordPress is written smart enough to ignore revisions while rendering the front end and. In addition, MySQL queries are written well enough so revisions don't actually slow them down.

However, post revisions will consume space in your WordPress database. Revisions are practically full copies of your posts, so if you have hundreds of posts this means you have few hundreds revisions stored too.

Removing your post revisions is a great way to reduce the size of WordPress database without sacrificing any actual content. To do this open the WordPress wp-config.php file and add the following configuration line to it above the "/* That's all, stop editing! Happy blogging. */" line:

define('WP_POST_REVISIONS', false );

Doing this, however, will only tell your WordPress application to stop storing new post revisions. If you want to delete all the existing ones, it's a good idea to use the Bulk Delete free plugin or a different one with similar functionalities.
