In previous post I talked about do you really need Post revision feature in WordPress, and we realize WordPress users finally understand that using WordPress post revision feature does not help them. specially when editing your post several time, and your database size is increasing with the useless revision posts, which you might not need.
Revision control is a wordpress plugin, which limit your wordpress post revision or optionally you can disable the wordpress post revision feature. I will suggest use the limit feature up to 2 count, or disable only if you are very much confident with how you use wordpress.
Here are screenshots of the Revision control plugin
What other tricks do you use to optimize your blog database?
