Depends on how many communities do you subscribe too and how much activity they have.
I'm running my single user instance subscribed to 20 communities on a 2c/4g vps who also hosts my matrix server and a bunch of other stuff and right now I mostly see peaks from 5/10% of CPU and RAM at 1.5GB
I have been running for 15months and the docker volumes total 1.2GBs A single pg_dump for the lemmy database in plain text is 450M
I subscribe to a few more communities and my DB dump is about 3GB plain text, but same story, box sits at 5-15% most of the time.
How much storage did it use overall? I had one instancs running on a 40gb HDD VM and it ran out of disk space in like 2,5 months. From what I've seen it was a mixture of 66,6/33,3 postgres/ images and other media. Didn't had the time to learn how to clean it up and prevent it from happening again after a month. All happens like may to August last year.
It's sitting at around 46GB at the moment, not too bad.
Instance is a year and a few months old, so I could probably trim down the storage a bit if needed by purging stuff < 6 months old or something.
I think it initially grows as your users table fills up and pictrs caches the profile pictures, and then it stabilizes a bit. I definitely saw much more growth initially.
