I tried UpFront recently and the interface looks great! On the other hand, it loaded so slowly that my workflow was alarmingly impeded. I was running the plugin on a site that has less than 10 plugins installed, so it wasn't an issue of the system being choked up with inefficient code. In fact, the particular VPS only has this single site on it and I've used every WordPress performance technique in the book. No joy.
Is there any news on the performance aspect of UpFront? And is there a good reason to stick with UpFront rather than going with Divi?
Thanks for any insights!
