I notice on a speedtest on GTMetrix that our CC6 site is much slower than our CC4 store. We have GZIP enabled on our CC4 store and leverage browser cache plus most of the css, javascript and html is minified. I was just wondering what the best approach with CC6 might be? I've also noted in the report that serving scaled images and image dimensions is a big fail, I'm guessing this is down to Foundation and that there is not really a work a round for this. Thanks
