TPLink WDR3600 OpenWRT wireguard throughput benchmark
TechOverflow tested Wireguard bandwidth / throughput on the TPLink WDR3600 with OpenWRT 21.02, based on a standard iperf3 TCP benchmark. We did not use Pre-shared keys in this setup.
So far we were able to verify that the Wireguard bandwidth is approximately 27Mbit/s (unidirectional), measured using iperf3.

iperf3 -son the WDR3600 and
iperf3_client.sh
iperf -c [IP address of WDR3600]on the client.
