This is obviously quite a small community, but runs on a $14/mo DigitalOcean droplet with 1 premium vCPU and 2GB of memory. It would likely run well on a cheaper droplet, but I want things to feel very fast 
I'd also be interested to hear how Waterhole scales up in terms of server resources!
Quick question. Do you run Redis? Just wonder if setting it up is worth for small communities.
