I wonder if it could run Wireguard well. I've been too cheap to replace my Raspberry Pi 2 with a Raspberry Pi 4 for my Wireguard router. My Pi 2 is struggling to saturate its 100/100 interface.

Doubtful. Like the RaspberryPi 2, it also has a quad core A7 CPU. If you are looking for a bit more power, you need to consider something with A53. That said, I'm surprised you are having issues, considering I have done over 200Mbps using a MT7621A with its 800MHz MIPS CPU.

  Yeah, I remember reading that people were getting better results than I was. Not sure really what's the issue. I am doing some IP translation to have kind of an alias subnet for my home network when going through the VPN. So maybe that's the issue. I did note that the CPU was getting hit hard when I was running iperf, so I've assumed that my bottleneck is there. I think I was hitting 60+ Mbps though, so it wasn't all bad. However my home connection is 1000/100, so going above 100+ isn't going to mean much. Which is why I've been too cheap to invest in a Pi 4; not too great of an improvement for 55+ EUR investment.

Check out the nanopi r4s instead for that kind of use

I use one for pihole (with DoH) and wireguard. For pi-hole, i filter around 10 devices, but i do only one wireguard connection at time. CPU usage is really low. I can have full bandwitdh usage on my 200/80 connection.

The Ubiquiti EdgerouterX can run wireguard beautifully with an easy to install package from github. $60 from most retailers.

  It really can't run Wireguard beautifully. I have one and it's the reason why I'm now running Wireguard on a Raspberry Pi 2.

    Hmm. We've had a pretty good experience with it on somewhat large deployment in the field. What issues did you run into? Just not fast enough? Or functionality/configururation issues?
    - Hamuko 6y ago
      Not fast enough. And the last time I went away from home for about a week, the Wireguard tunnel on my EdgeRouter X broke so bad on the second day that the router interface became completely unreachable, the static host mapping broke and connected clients were having DNS issues. It needed a hard reboot, which was hard since I was hundreds of kilometers away. I can't say for sure that it was because of the Wireguard tunnel, but considering how low my Wireguard usage was before without issues, it's my main suspect. After I got home, I hard rebooted the EdgeRouter and then migrated my DNS and Wireguard off of it. I've decided that the less things that my EdgeRouter X does, the better it is. I've also decided that if I get a new Raspberry Pi for my Wireguard duties, I'll leave the old one as a backup because you just never know.
