WireGuard slow? Or... what should I expect?

[Vlijm]

Hey all!

Running OPNsense 20.1.7 on a GX-424CC with 8GB RAM and a dual port Intel i350 ethernet adapter.
My connection is 1000/1000 fiber.
In a speedtest I get around 945 up and down.

A while ago I set up a WireGuard server which works great. The only thing that has been bothering me is the speed.
When connected to my WireGuard server I get around 100 down and 140 up. It does not matter if I am connected to WG on my own network, or from an external network.
Since WG is praised for it's speed, I am kinda disappointed to be honest.

Are these speeds what I should expect from this system or should I be able to reach (much) higher speeds?
I hope someone can help me out here.

In a Lab with 10g and moderate Xeons I achived 1,9gbit

Is that "1.9Gbit" so almost 2Gb on a 10Gbit link?

I know WireGuard in itself is capable of high speeds, but I would like to know why I'm only getting 100/140 in my setup. Is this a limitation of my hardware, or is something wrong.
I'm quite sure that moderate Xeons are much more capable than the GX-424CC, but I'm using this setup as my home router :)

I dont know your hardware, but I know that IPsec is only a Bit faster on the same hardware.
