Why WP-Sweep vs WP-Optimize?
You may be wondering why are we writing about WP-Sweep when there is a very popular WP-Optimize plugin available that does nearly the same thing.
Well that’s because it’s coded by a well-respected WordPress developer, Lester Chan.
Also because the main distinguishing characteristic of WP-Sweep is that it uses proper WordPress delete functions as much as possible instead of running direct delete MySQL queries. Whereas the WP-Optimize plugin uses direct delete SQL queries which can leave orphaned data left behind.
Looking through WP-Optimize and they are using SQL query to delete post revisions which means there will be orphaned data left behind.
