Virtual private networks / Slow Kernel-based WireGuard Performance
« on: August 02, 2021, 10:56:24 am »
I have 2 OPNsense servers running a WireGuard site-to-site tunnel across a 1Gbps connection. I've installed wireguard-kmod and previously was able to see approximately 850Mbps or so of iPerf across the connection. However, I've installed updates over the last couple of weeks and now only see approximately 400Mbps via an iPerf test. I saw the slowdown with both 21.1 and 21.7.
I'm not sure why wireguard-kmod has become much slower, but I'd like to try reverting the wireguard-kmod package to a previous version. I'm having trouble figuring out how to do this though.
Any recommendations?
Thank you.
