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.

During the test, top consistently showed 0% idle CPU load, with the load being approximately 51% sys and 49% sirq.

The commands in use were

on the WDR3600 and

on the client.
