speedfusion traffic slower than other traffic on att network?

In the spring, speedfusion traffic was running at about the same speed as a straight speedtest over my ATT LTE-A wan connection (taking into account ~19% overhead)

This month, my ATT LTE-A connection is running faster on a speedtest, up from 20-30 mbps download speed / 20 mbps upload speed last spring to 65 mbps download speed, 20 mbps upload speed at night on speedtest.net. Quite a nice improvement on speedtest.net

However, speedfusion traffic is running at only 15 mbps down, 20 up now over that LTE-A wan now, quite a bit slower!

Anyone see something like this over att this fall or have any ideas on what to start tweaking?
