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.
