Apu2 performance

I have questions about the performance of the following devices:

Device name: apu2
openwrt version: v19.07.0-rc2

Connection form: PPPoE wired LAN
WAN MTU: 1492
Enable software offload
Enable irqbalance

The speed should be about 800Mbps,

With SQM (cake + peace of cake): 220Mbps
Without SQM: 500Mbps

The result is as above.

Is there something wrong with the settings?
Ideally, there is SQM, and it is ideal to output about 700Mbps.

Please, have a look at @jeff's excellent performance testing and comparison thread. I believe the AMD x86 device in the tables is an apu2: https://forum.openwrt.org/t/comparative-throughput-testing-including-nat-sqm-wireguard-and-openvpn/44724
Based on that thread I guess you might be able to get more than 200 Mbps with SQM but as so often, "conditions apply".


Thank you for the answer.

Additional research showed that the CPU scaling was not working properly.
Speed will peak off.
How are you set up?

Is there any problem with the following settings?

echo 35 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor

try this (in /etc/rc.local)

echo -n "performance" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor >/dev/null 2>&1 || true
