Qualcomm Fast Path For LEDE

I maxed out ingress and egress at 800Mbits
Since Fast-Path can do 900Mbit
cake+layer_cake = 571 Mbits/sec
fq_codel+simple.qos = 663 Mbits/sec
I am using GUI to test on jperf
On dslreport speedtest I can get A+ for google chrome but not for firefox.
I think the service is quite cranky and inconsistent.
