This life-saver plugin adds a button to the dashboard when installed that allows the administrator of the website to perform certain site optimization tasks such as removing old post revisions, minifying images, removing trashed comments and lots more from the comfort of their own dashboard.
Want to optimize the tables in your database? No problem, just install this handy plugin and with no configuration required you can do that with just the click of a button. If you have a WordPress site and want a boost in performance, as long as the issue(s) causing the slowness are not very uncommon and strange, this is the plugin for you.
