This plugin does what it is made for. After first run my blog sites in the complete MU installation gained up measurable speed and performance. Issues of pages stalling during loading disappeared. I run it regularly now and I am very happy with it.
I installed this plugin to solve the bloated database issue (100Mb size on a site with a few pages). It does what it says on the box and does it without errors.
I also love it that it is integrated with Updraft backups so I can take a database backup before optimising the tables. But again, never had any issues with it, it just magically reduces the db size with a single click. You can’t wish for more. 
Thanks for the great work!
I use WP-Optimize for many years and it never let me down. Can highly recommend to use it.
@devs: Keep up the good work!
Had this running for some time now, set to auto every 2 weeks. No problems, working fine. Thanks
