<p>WordPress stores a lot of excess information in your DB (like post revisions, auto drafts, spam and trashed comments, transient site options, etc.).<br />
Of course there’s a reason for that and some of this data is needed once in a while, but most of it is not critical. It just sits there taking up space and never being used.<br />
Over the time as your site grows the volume of this unused data grows with it making your database unreasonably huge thus effecting the site’s overall performance.</p>
<p>Using WUCO you can easily and safely clean up your database from those useless entries. With a single click you can remove revisions, drafts, auto drafts, orphaned post and comment meta, transient data and much more. You can also schedule the cleanups for later and they will be run automatically keeping your WordPress site clean and shiny.</p>
<p>And as all the best things in life WUCO is and always will be absolutely free.</p>

Optimize Database after Deleting Revisions

In principle this would be an excellent plugin but it always leads in time-out errors. In our view, the problem lies with the execution of the optimization process itself. There is no safeguard against time-out errors. This should be fixed as there must be better ways to code this. 

Good plugin but leads to ongoing time-out errors


Plugin works exactly as described. Thanks! It was easy to configure and I especially like the ability to remove all revisions except for XX amount, which makes it great for cleaning up existing sites where you've reduced the number of revisions, but the database still contains heaps of older revisions.


Easy to use with great results
