There are different server implementations. I run tuwunel and haven’t had problems. It seems about as performant on my VPS (8GB RAM, 4 CPUs at 2.4 GHz, hosting other services not just tuwunel) as matrix.org was when I used that.

It’s great to see a mainstream OEM work with GOS. I really hope Motorola will make phones with an actual headphone jack. That’s my no. 1 complaint about modern Pixel hardware.
