SQM settings look good. You can use these commands to check if your CPU settings are working and that irqbalance is enabled (usually have to restart after putting it in the rc.local file)
cat /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
cat /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor
cat /etc/config/irqbalance
I run packet steering too to balance the network load:
uci set network.globals.packet_steering=1; uci commit network
You can check the global settings here after you enable it:
cat /etc/config/network
Those are the best tweaks I’ve found for the r7800. I’ve been able to shape up to 450-500mbps total. The next major breakthrough is waking up the NSS CPU cores to get hardware acceleration working, more work needed there but quarky has done great work:
