Jeff does explicitly call this out in his video, but as sibling commenters say, it's really a matter of whether that's enough for you. Even 20 Mbit symmetrical

Jeff does explicitly call this out in his video, but as sibling commenters say, it's really a matter of whether that's enough for you. Even 20 Mbit symmetrical would be more than enough for me to run a stream from a Plex server while serving other web or SSH traffic easy enough. What you do say though brings up a great point though - if you ran this on a Pi and you're not getting the performance you need for your use case, check CPU utilization on the Pi, and consider running your VPN on a device with more oomph.
