I kind of want to self host a lemmy instance. What are the requirements for a single user lemmy instance?

    Numbers from my instance, running for about a 1 year and with average ~2 MAU. According to some quick db queries there is currently 580 actively subscribed communities (it was probably a lot less before I used the subscribe bot to populate the All tab).

    SELECT pg_size_pretty( pg_database_size('lemmy') ): 17 GB

    Backblaze B2 (S3) reports average 22.5 GB stored. With everything capped to max 1 USD, I pay cents - no idea how backblaze does it but it’s really super cheap, except for some specific transactions done on the bucket afaik, which pictrs does not seem to do.

    According to my zabbix monitoring, two months ago (I don’t keep longer stats) the DB had only about 14G of data, so with this much communities I am getting about 1.5G per month (it’s probably a bit more as I was recently prunning stuff from some dead instances).

    Prometheus says whole lemmy service (I use traefik) is getting within about 5 req/s (1m average) though if I go lower it does spike a lot, up to 12 requests within a second then nothing for few.

    You really only need Storage. Backblaze B2/Wasabi/Cloudflare R2 if you can afford it, or just get a Hetzner storage box, attach it to the VM, run Minio and off you go.

      Attach it to the VM

      Is this possible only with the extra, bought storage boxes ? Or is this possible even with the free 100G backup boxes offered with each dedicated machine ? (Or is this just nfs mount?)

      We have a dedicated machine in a project from Hetzner with big raided hard disks but the latency is starting creep up on us, moving some of the data off to the faster ssd/san boxes would be rather helpful.

    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 have one running on the equivalent of a pi. It works no problem. The biggest issue is the constant io and network traffic but it’s not terrible.

    I wish there was a only poll once every x amount of time instead of the constant polling, but it’s a good solution. I use lemmy.world as the main account and the other account when I need to post under my real name with some projects I run. Plus it makes for a good development instance since I work on lemmy from time to time

    Raspberry Pi will handle it.

    It’s all about the storage space. Processing requirements are minimal.

    I am wondering if it is that good to have single instance for feddiverse. It hurt feddiverse servers to send to yet another location, or is it more like p2p so it scales well?
