I've run a single-user pleroma server since January 2019. I ran it on a digitalocean droplet with 2 GB RAM, and then an AWS instance (t3.small, also 2 GB) for the better part of two years; I recently switched to a t3.medium. Beam's current process size: 250MB resident, uses 5-7% CPU.

I discard remote posts after 120 days, and my database (using PostgreSQL 15, no RUM indexes) takes up just over 5.4 GB (as reported by `pg_database_size`). It's grown a lot faster in the past couple of weeks. I follow 245 accounts.
