I've been maintaining a misskey server (here) and it's connected to ~10,000 instances with 2.6 million post records. It likes to expand into 16GB of ram then relaxes into about ~8GB. I am fairly certain it would be ok with fewer memories.
My biggest gripe about fediverse is the storage. I have to cull data so i don't have to monkeypatch drive size increases on the hypervisor. median storage is about 300GB give or take.
What's wild is that it was only about 2700 instances in november, but a large mastodon instance imploded and the userbase went everywhere, so as people posted "here i am" i added them, and that ballooned the connected instances.
