I wonder what the stats on running a lemmy instance are.
How much time needs to be invested, how much data storage is needed, what kind of traffic volume is to be expected?

Wait, nothing lasts here on lemmy for more than 6 months!? I swear I’ve seen much older stuff here?
The person you replied to is wrong. That 6 months has nothing to do with removing old comments or postings.
Cool! What’s the 6 months thing about then?
The programmers were using it to debug things. Right now it’s just doubling the storage ;)
Someone asked the developers 5 days ago about it: https://github.com/LemmyNet/lemmy/issues/3103
Pretty sure OP-comment misinterpreted the code. My best guess is that they’re simply pruning an index or something like that.
Lemmy will clean up posts older than six months.
That’s a wrong interpretation of that code. There is a table call ‘activity’ that is a debug log. It does not clear comments and postings to truncate that table at 6 months. The app doesn’t read from that table, it only writes to it.
I would love to hear the answer to this as well. I guess it’s heavily dependent on how many users you have and if they are uploading images or just text, or just lurking.
I think if you did not allow signups it would probably be extremely minimal.
https://sh.itjust.works/post/4706 gives some info on the hardware sh.itjust.works is using.
Honestly, I’m interested in knowing some of this too.
https://join-lemmy.org/docs/en/administration/administration.html says about 150GB RAM and negligible CPU usage.
I assume an instance with users subscribed to active communities requires meaningful storage, but I’m not clear the sizes we’re talking about (what’s data growth per/day been like for some of the larger communities).
EDIT: Likewise, I’d love to know if that 150GB RAM is fixed or whether that number grows with use.
That page says 150 MB (0.15 GB), not 150 GB (150,000 MB) of RAM.
I suspect that it depends on if you’re accepting other users and or communities. If so, you’ll have to be global mod and probably spend time sorting out mod reports etc.
If you’re just setting up an instance for yourself, it’s probably easier but you’ll need an account somewhere else to discover communities and index them back to your instance.
Mines been running for a few days now and with some image heavy communities shortage is up to 1gb for 1 user. I have it on a separate volume that can be expanded if needed.
The boring answer is: It depends.
Is all about the traffic and number of users which is dynamic and not same for everyone.
If it’s only for yourself then you could host an instance on a raspberry pie for sure.
If you’re looking to create a big instance with many users you’ll need a lot of power and storage.
It’s almost impossible to put the requirements down on paper. Sure you could estimate with enough data.
Lemmy starts out empty, and if nobody joins any communities it doesn’t start getting any data. It doesn’t bring over old data, so if you install it on July 1, the data just grows from July 1 onward.
Lemmy is going through some growing pains, performance wide and federation data sharing wise. Hopefully 0.18 will be out within a week or so and and some of the worse performance issues improve.
