I'm using Hummingbird and not getting any better Google Page Speed reports. Still below 50 on both mobile and desktop. I need page speed scores in the 60 to 70 range. I saw a slight change, but not what I was expecting. On GTMetrix the site has gone from 14 sec to 10 sec on an unthrottled connection. But on 3G there is no improvement, still in the low 20s.
