I’m using W3 Total Cache and i’m really happy with, page speed and Yslow are two times better and front end navigation is much more better. I was about to change theme, dante was really to slow, too bad lot of work on http://www.loujett.com/shop, more coming. Speed is quite ok now and could be better !
When minify css and/or js front end is broken and gmetrix very low. Please some feedbacks, advices for the minify settings, which files are not good to be minified (jquery.js…) ? If you want to have a look to settings you’ll find access in private message.
