Database optimization is a useful tool when it comes to speeding up your site. LSCWP's DB Optimizer (available as of v1.2.1) gives you an easy way to execute some of these tasks in your WordPress database. Learn more on our blog.

Manage Tab

LSCWP Database Section Manage Tab

You'll notice that some of the buttons have teal check-marks while others have red X's. The check marks indicate that the area has already been cleaned-up. If you see a red X, that is your opportunity to do some optimization.

Clean All

Press this button to clean up everything at once. It executes all of the listed cleanups, except for Optimize Tables and Clean CSS/JS Optimizer.

Post Revisions

Removes all old post revisions from the database. You will sacrifice your ability to go into any of your post and restore previous versions of them. Only the currently-published version of each post will be saved.

Orphaned Post Meta

Cleans up any metadata records that were left behind from previously deleted posts.

Auto Drafts

When you edit a post, WordPress automatically saves drafts now and then. This is to protect you in case you unexpectedly lose your connection, or your computer crashes. If you know that all of your posts are either published or saved correctly as drafts, then it is safe to remove the automatic drafts.

Trashed Posts

This option permanently deletes any posts or pages that have been placed in the Trash.

Spam Comments

There should be no need to keep comments that have been marked as spam. This option erases them permanently.

Trashed Comments

This option permanently deletes any comments that have been placed in the Trash.

Trackbacks & Pingbacks

When other blogs link to you, it can create trackbacks or pingbacks. Some WordPress themes display these in the comments section. If displaying these external links is not important to you, press this button to clear them from the database.

Expired Transients

Transients are the result of a form of caching that can happen in the WordPress database with the results of remote API calls. This option clears all of the expired transients from the database.

All Transients

This option clears all of the transients in the database, whether expired or not. NOTE: It is normal for there to still be some transients left after cleaning. Transients are caused by plugins, and are regenerated every time you reload a page.

Optimize Tables

Use this button to optimize the database tables.


This function is not included in a Clean All.

Clean CSS/JS Optimizer

If you use the Minification and/or Combination functions for CSS and/or Javascript, you can clean up the related data with this button.


This function is not included in a Clean All.

DB Optimization Settings Tab

These settings give you more control over what is deleted during Database Optimization.

Revisions Max Number


Specify the number of most recent revisions to keep when cleaning up revisions.


If you would feel more comfortable having one older revision saved for each post, set this to 1.

Revisions Max Age


Revisions newer than this many days will be kept when cleaning up revisions.


Set to 30 if you want to keep any revisions from within the last thirty days.
