OpenVPN performance compatability



  • I purchased the SG-1000 to use in my home. I have a 100mb Cable Internet connection and I typically get about 60-70mb throughput when I do NOT use OpenVPN out. I have my device setup to do an OpenVPN connection using Torguard.net as my provider. I use multiple gateway assignments to only send certain traffic out the VPN interface and all other traffic out the standard WAN interface. I've recently had problems with the VPN interface where I'm only getting about 3-4mb throughput. I've worked with the Torguard.net support team and they don't know what the problem is but they just told me that they believe that it's because my SG-1000 only has a 600mhz processor and the routes that I'm going out (I live in Germany [U.S. Army stationed here] and I VPN back to the USA for my Netflix, Amazon, Hulu and so forth). I have a friend who uses the same VPN provider as I do and he gets about 17-30mb. So, my problem is either my Internet provider or the SG-1000. My question to you is what speeds does the SG-1000 support when using OpenVPN? Is Torguard.net correct in their assessment?  Thank you



  • You will indeed have very limited speeds with the SG-1000. If you want fast OpenVPN doing 50Mbit or more, you currently still need a powerful Intel CPU.



  • John, Thanks for the quick reply. Well, I guess I didn't realize the SG-1000 was so limited…my bad for not researching it better I guess. I do have a server that I am running ESXI on based on a Supermicro A1SAi 2750 Atom C2750 Motherboard. If I carve out a VM on that and run it do you think it would be better? That is a 1600mhz Atom processor and I could give it 2gb RAM and it runs on an SSD...so performance should be OK. I run 2 Windows 2016 Domain Controllers on it now with spare resources to use for other things...

    Yes, the C2750 will work fine. The SG-1000 isn't all that limited, just not really suitable for high speed OpenVPN. I suppose for people not using OpenVPN it's sill a really good choice.



  • I have a friend who uses the same VPN provider as I do and he gets about 17-30mb.

    And what hardware your friend is using?

    So, my problem is either my Internet provider or the SG-1000.

    The SG-1000 unit will be the bottleneck but there fore it is a very small hardware and also limited for that art of work
    (vpn encryption) in my eyes.

    My question to you is what speeds does the SG-1000 support when using OpenVPN?

    We all can only imagine it, because the cables, the lines, the actual amount of VPN users at the same time and
    other criteria´s will be also into the game.

    Is Torguard.net correct in their assessment?  Thank you

    I would say yes, they have still more reserves for many more customers or a higher network load and if not
    they will find many customers changing fast to another vpn provider at this days. So why should they do anything
    that is harming there business?

    I would try out at first another VPN method called IPSec and if this might be not bringing the wished effect
    I would change the pfSense box against another one that is more strong.



  • @ John, Ok I will set up the Atom box this weekend and do some more testing, hopefully it's better.

    @ Frank, My friend is using an old 3ghz desktop computer and that's all that's running on it. I think you're right, it's the hardware. I will change it and see. Danke!



  • You could keep the SG-1000 as just a router/firewall (always a good idea to keep such things on their own hardware) and just run OpenVPN on your Atom box in a VM.

    There are many Open VPN appliance builds that are perfect for virtualization - starting with these from the OpenVPN site itself:  https://openvpn.net/index.php/access-server/download-openvpn-as-vm.html



  • I am still looking for a barebone or minipc, (nearly) silent that can reach 60-70MB/s OpenVPN (256) for under $250/£200. No 2nd hand or repurposed hardware or "run your openvpn from another place". I just want one small router, not a big collection of devices which would only increase the number of possible points of failure.



  • just search the forum, there's a very large number of options in your price range for what you want to do.

    I own this one, no problem to reach 120Mbps OpenVPN (256)
