    Roughly 2 GB of RAM, 2 cores of CPU. PieFed.social has 8 GB and 4 cores for 150 users and that is more than enough power. We haven’t had a very busy instance with thousands of users so the only scaling tests have been to do with federation - “what happens if I join every community”. The UI is very lightweight, tho.

    It really depends how many communities you subscribe to. A single user instance might be able to use less.

        Yeah, sort of. The total number of subscriptions (by all users) determines the load caused by federation. If you subscribe to 200 communities then I subscribe to the same 200 the federation load will not increase.

        So once an instance has more than a dozen users pretty much every community that exists will be subscribed to and adding more users will not increase federation load (but it would increase load caused by the UI)
