OpenVPN performance

  • Does anyone have any comment on OpenVPN performance in 2.2 vs 2.1 branch?

    Can OpenVPN use more than one core?

  • Rebel Alliance Developer Netgate

    Each separate instance would use one core each, so if you have a bunch of site-to-site tunnels static each on it's own tunnel it would spread the load around.

    IIRC multi-threading is on their todo list for OpenVPN 3.0

    Their Access Server product already has a way to spawn multiple daemons for handling client connections somehow but I don't believe that feature has made its way into the community edition.

  • Ok. Thanks.

    Seems like I have to update the trusty old Intel D2500CC then. Currently it manages about 80 Mbit/s throughput on one core.
