Pie has a default latency target of 20ms, fq codel 5ms. (But the fq code target matters less as the target only applies to queue building flows)</p>
<p dir="ltr">A packet takes 13ms to transit the device at 1mbit.</p>
<p dir="ltr">There is a change to fq codel in this release that should make fiddling with target a low speeds less needed. (But might have other problems) Still a comparison at roughly the same target vs a vs pie in your environment would be very interesting.</p>
<p dir="ltr">I suggested 25ms as a test (as pie never makes 20ms anyway)</p>
<p dir="ltr">I came close to inserting a simple formula to start increasing the target below 4mbit in this release.</p>

I would love to hear whether that worked or not (I am not able to test anything myself). Maybe posting the output of "tc -d qdisc" and "tc class show dev ge00" would help. Good luck…<br>
