When you do your tests, do you set the = shaper to a high number and see how high actual throughput goes, or do = you do it some other way? Just in case, I tried setting the ER-X to = 350Mbit. htb+fq_codel topped out at 149Mbit, and with c/burst 96000 186 = Mbit, so in both types of tests it was about a 25% increase, not small, = but unfortunately not 2x!
