      I have a question regarding your hardware recommendation. I'm just about to complete a DSL contract either 50MBit / s or 100MBit /. I would like to use OpenVPN with 256bit encryption. I would like to have full download speed with VPN because all traffic is used. Do you have a recommendation which hardware can do that? I use it only at home and 95% only with Wi-Fi. anyone a low-cost recommendation? :)

        I use Astrill, and when i sometimes use utorrent it can download at 22-23MB/ s but avarage is more 17-18 with snort enabled

        This is my CPU for the moment as i will wait to upgrade to an xeon and intel mainboard.

            Is that with FastIO enabled and send/rec buffers increased?

              @stephenw10 Just FastIO. I have not done any buffer adjustments yet.

                FastIO made the biggest difference in my testing. Setting the send and receive buffers to 512k did make some improvement. There was little to be gained setting them higher than that. In my test at least. More testing is always good. ☺

                Those numbers are pretty good already though.

                  I am very impressed with the cpu. Motherboard not so much. Plenty of available PCIe lanes for dual Intel gigabit lan. And a pcie x1 slot instead of x16. The realtek gigabit lan couldn't muster over 600mbs. Gigabyte announced a J5005 board earlier this year, but they never released it.

                        Hi,

                        Here is my new results:

                        time openvpn --test-crypto --secret /tmp/secret --verb 0 --tun-mtu 20000 --cipher aes-256-gcm
                        

                        Intel i5-7400 4 x 3.0GHz - TDP 65W -CPU Mark 7382 - Single Thread 1957
                        3200/8,05 = 397 Mbps OpenVPN performance (estimate)

                        --- 24.11 ---

                            Nice. Are you able to test a reality figure on there at all?

                              In linux with a client running on the same machine in kvm, it hit 1100Mbps. (So, zero latency internal network, but with the load of being both client and server.) I'd not expect to see that on a real link, as I don't think OpenVPN will keep enough packets in flight to fill the pipe, but the hardware can do it. That said, I'd pick a newer i3 if I just wanted a firewall with openvpn; the ryzen is overkill for that, and an i3 should hit the same numbers for less money.
