What's the throughput like on a Raspberry Pi?

Here is someone's benchmark from reddit: https://www.reddit.com/r/WireGuard/comments/eeafds/wireguard_throughput_on_raspberry_pi_4/ https://www.reddit.com/r/WireGuard/comments/eeafds/wireguard... (tl;dr "Avg: 829 Mbps")

  That's for a Raspberry Pi 4, which should have a pretty drastic performance difference from the Raspberry Pi 3 mentioned in the article since only one of those has proper gigabit Ethernet. It does seem pretty good though. I'm having trouble getting past 25 Mb/s in, 100 Mb/s out on my Edgerouter X.

    Rpi 3b has proper gigabit Ethernet though. Edit: 3B+. My bad.
    - Hamuko 7y ago
      It doesn't. Edit: It doesn't.
      - spmurrayzzz 7y ago
        The 3B+ does though, IIRC (w/ PoE support too)
        Hamuko 7y ago
        IT DOESN'T

        It doesn't. The ethernet is connected to a USB 2.0 bus. Yes the link trains at 1 gbps, but it's limited by the slow bus.

        It's basically a 1 Gbps PHY connected to 480 Mbps USB 2.0, so it's 240 Mbps Ethernet.

    Sure but that article was about using it on a LTE connection and the GP was asking about Pi in general. In the articles setup it's going to be bottlenecked on the cellular network anyway. (The Pi 3 also is 4 years old now and you wouldn't want to buy it today)

I was only able to get ~60mbps with OpenVPN through a hard wired Raspberry Pi 3 connected to Google Fiber, due to limitations of its bus. The 4 is supposed to be actual gigabit, but I have not yet tried it out to confirm.

  I'm trying to set it up on a RPI4 as an 802.11ac wireless router, to verify this. If it manages 100mbps+ then it'll be a cheap replacement for my current router.

    Are you keeping a write-up of your progress anywhere? Would love to see how this turns out.
    - eatbitseveryday 7y ago
      Not yet; but that's a good idea. Thanks for the nudge :)
  - dicknuckle 7y ago
    are you using OpenWRT or something else?
    - eatbitseveryday 7y ago
      Starting with Ubuntu for now, and hostapd.
- kingosticks 7y ago
  Which bus limits to 60mbps? The USB limitation shouldn't be anywhere near that low.
  - samsepi0l 7y ago
    The USB bus on those is shared with all devices

I’ve been using a pi3 for about a year as a full time VPN on my cell phone and laptops. 3 is only 100mbit eth, but I’ve had almost no issues with it. Connects fast, no problem streaming HD video or cloning huge git repos. Maybe when I get home today I’ll take some measurements.... But my biggest issue is the trash Powerline Ethernet between my router and rest of my network.

  I have issues with my wireless signal just crapping out from out of nowhere from time to time. Usually in specific spots in my home. I setup a repeater (thinking a mesh network might be the better choice, but this was a much cheaper temporary solution) but it still sometimes happens. The ethernet is fine on the other hand. I run OpenHAB and Pi-Hole all on a RPi3 on ethernet, no issues so far.
