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.
- eatbitseveryday 7y agoI'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.
- bananaeater 7y agoAre you keeping a write-up of your progress anywhere? Would love to see how this turns out.
- eatbitseveryday 7y agoNot yet; but that's a good idea. Thanks for the nudge :)
- dicknuckle 7y agoare you using OpenWRT or something else?
- eatbitseveryday 7y agoStarting with Ubuntu for now, and hostapd.
- kingosticks 7y agoWhich bus limits to 60mbps? The USB limitation shouldn't be anywhere near that low.
- samsepi0l 7y agoThe USB bus on those is shared with all devices
- kingosticks 7y agoTrue. It does depend what else you are doing with the pi. Something like a USB hard drive could account for that poor performance, especially if you were upload from/downloading to it.
- bjoli 7y agoI don't know, but you get the extra limitation of USB2 being half duplex. USB2 is something like 480mbps. Add half duplex limitations and just general overhead compared to theoretical max. I can see how some network protocols become limited to 60mbps.
- vardump 7y agoRaspberry Pi 3 can do at least 250 Mbps. Perhaps it's limited by something else, like crypto or your actual connection?

- tjoff 7y agoOpenVPN is extremely slow, same setup with wireguard is guaranteed to be much faster.
- willis936 7y agoI just ran iperf from my Pi4 to my Ubuntu VM in the same LAN five minutes ago. 850 Mbps symmetric with no VPN.
- bscphil 7y agoI get 940 Mbps for two devices on the same switch.
