Testing with a very similar IPQ4019-based EA8300 (primary difference in SoC being that it supports PCIe for a third radio), using iperf3 from the router to a local server I see:
- OpenVPN -- 23-25 Mbps
- WireGuard -- 260-300 Mbps
There is more variation in the WireGuard results that I would like to quote that as a "hard" number (occasional runs under 260 Mbps). I'm checking to see if it is due to irqbalance not being installed.
master build from last night's source.
(Using irqbalance did not improve the results for WireGuard.)
