Wireguard is easier to configure and use and in my informal tests performed at close to line speed, around 870 Mbs on a gigabit network.

This is extremely fast for an encrypted network given most other solutions tend to take a severe toll on performance often operating at 140/180 Mbs on gigabit networks.

The only drawback currently is it's a kernel module and needs to be compiled, which makes setup across systems a bit involved, however there are ongoing efforts to merge into the kernel.

It's unfortunate innovate open source tools like Wireguard that add a lot of value to networking and clustering are not more well known.
