Help with bufferbloat on R7800 using OpenWrt

[atownlede]

I found some CPU utilization problems with cake & piece_of_cake on my R7800 router. The default CPU frequency scaling really interfered with the SQM shaping.
Some notes over here in this thread:

SQM fine in 17.01.4, can't keep up with line speed in 18.06 (Netgear R7800)

Thanks, some good hints in that thread. Setting the ondemand control values helped a lot on its own. Adding in software flow offloading and I'm up to line speeds for download testing and I get lower CPU frequency when idle, for fq_codel/simple. cake/piece_of_cake still aren't up to line speeds. root@LEDE:~# cat /etc/rc.local # Put your custom commands here that should be executed once # the system init finished. By default this file does nothing. echo 35 > /sys/devices/system/cpu/cpufreq/o…

I'm in Boston area with RCN cable modem with measured line speeds about 260/16.
