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 -

Jason / Simon - great work on Wintun!
