If one is to run this relay, how much compute resources are required to do so?
Latest push has all this. Please test. New release soon.

As much as you set in the limits 😀
That's the cool thing. It's configurable.
It depends on how many events and requests you're getting of course. A small relay can probably run fine on a pi.
