Self hosting resource usage (RAM/CPU/Disk)

[applejag]

Hello!

On the documentation page "Run your own server" (https://docs.joinmastodon.org/user/run-your-own/#so-you-want-to-run-your-own-mastodon-server) there's this great list of things to make sure you can setup, stuff like VPS, DB, and BLOB storage.

What I find hard to read up on is how big the assets needs to be.

More concretely, this is what I find missing from the docs:

1. RAM usage
2. CPU usage (difficult to measure though)
3. Disk usage in DB (Postgres)
4. Disk usage in BLOB storage (ex: S3)

And all of the listed items on a minimal 1-user setup as well as some measure of how much is needed per user and per time.
I know all servers will use different amounts, but just some value to go after.

Like a recommendation of like "Expecting 0-100 users? You need at least 1 GB RAM and at least 5 GB of storage for the first ~year" or something of that sort would be very helpful.

Kind regards
