Do you mind sharing your hardware build/partlist?
I'm looking into purchasing something similar and i like your idle power usage of 13watts.Thanks.
Sure, I'm using a prebuild Lenovo M700 SFF that I got really cheap with a platinum rated PSU (to quote Lenovo's website: "ENERGY STAR 6.1, ULE Gold, EPEAT Gold, and 85% efficiency with 80+ Platinum power supply unit", I'm not sure that's saying all that much though). Specs are: Intel G4400 dual core, 4 GB DDR4 memory, it came with a HDD but switched it for a cheap Kingston SSD and I added an Ebay Chinese I350 T4 NIC. I unplugged the CD drive and USB connectors and some other stuff not used. Speedstep is enabled and the CPU is often running around 1.5-2.0 Ghz when idle. Now I've monitored it over a longer time, the average idle power consumption usage has been around 15 watts. The case is really cool as well, usually around 25 degrees.
When building yourself, it's probably best to get a Pico PSU and search for a power efficient motherboard.

You could trying out to enable PowerD (high adaptive) of not done yet, to get perhaps less then 15 watts back.
or did you enable the PowerD (high adaptive) option? -

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.

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.
