Hi,

I got some new Wintun (I used version 0.2) performance stats I would like to share. I have tested openvpn2 and openvpn3 (both with openssl) on the client against openvpn2 and proprietary openvpn3 server (which is openvpn3 with kernel acceleration). Cipher AES-256-GCM.

Server - proprietary openvpn3 
----------------------------------------------------

ovpn3 wintun   1.90 Gbit/s
ovpn3 tap6       890 Mbit/s

ovpn2 wintun    870 Mbit/s
ovpn2 tap6       440 Mbit/s 


Server - open source openvpn2
----------------------------------------------------  

ovpn3 wintun    670 Mbit/s
ovpn3 tap6       580 Mbit/s  

ovpn2 wintun    610 Mbit/s
ovpn2 tap6        450 Mbit/s


As you see, in every case Wintun overperforms tap-windows6 and approaches mind boggling 2 Gbit/s.

My openvpn2 wintun patch could be found here https://github.com/lstipakov/openvpn/tree/feature/wintun, and openvpn3 - https://github.com/lstipakov/openvpn3/tree/fix/wintun-fixes

Jason / Simon - great work on Wintun!
