We have been using Boostly for a couple of weeks now and the results are astonishing. Previously our site has been rather slow and immediately after installation it increased above average. We didn't have to do anything apart from the installation: nearly feels like magic! Having said this: it's not just the speed score. Our site also "feels" subjectively faster on front-end. Especially load time of imagery seems now instant without any delay. Highly recommended to everyone wanting to improve site performance!
