I got an email from WPX, that they give you a one-time only opportunity for optimization of your website, you just need to fill in their document https://kb.wpx.net/how-can-i-start-the-optimization-of-my-site/

Remember the days of struggling with huge speed issues when hosted at WA and that you couldn't get them to figure it out? I've spend countless hours on trying to get my site in order, not any longer. So happy to have switched!
