My ISP provides 1 gigabit downstream. Using a RPi4 to run SQM, I am finding that with either
fq_codel/simplest (750000 down and 22000 up), the best downstream I can achieve is around 565 Mbps. Watching
htop on the RPi4, I see core0 is consistently loaded >99%. I read about the RPi4 being able to shape gigalan symmetrical connections so am wondering why mine is falling short.
Can someone with a fast connection and a RPi4 confirm the claim?
I am using DSA to run two VLANs on this RPi4, so perhaps that is limiting me assuming others with the hardware/connection and confirm better downstream speeds.
EDIT: For this entire thread with the exception of the final post, I believe I had the SQM target on a bridged interface rather than on the physical one. Putting it on the physical one gave the lowest CPU usage so keep that in mind when reading everything else in the thread.
