Well, ideally each service would have their own dedicated resources to begin with. But, given all of the lemmy services + Postgres are running on 2 cores with 2GB of RAM, that’s pretty impressive.
Anyway, autoscaling doesn’t necessarily solve scaling issues without a lot of thought and planning. It’s not always as simple as throwing more hardware at the problem, as I’m sure you already know.
I’m not familiar with unraid.
I used the documentation over on join-lemmy.org to setup my instance, on ubuntu. main docs: https://join-lemmy.org/docs/en/administration/administration.html
Here are the docker specific instructions: https://join-lemmy.org/docs/en/administration/install_docker.html
With just me on the system, CPU is barely ever over 2 -3%. Load average looks good. Memory usage looks fine. You know what? Let me post some graphs for the past 24 hours, which, I’ve pretty much been on here for 24 hours straight. Again, I’m the only user on my instance.
I’ve mentioned this in a few other threads, but I’m tempted to fire up jmeter and push some load through my instance just to see how it behaves if I slam the system via the API. I just don’t feel like learning the internal API endpoints and all that right at this time though.
I’m running my instance on 2 cores, 2GB of RAM. Of course I’m the only one on there at the moment, but it’s running great, and I think it might even be fine with a single core.
As other have said, if you are planning to use it for your own “user’s home instance,” that should be fine. I’ve read a few people are running their instances on Raspberry PIs, which is pretty neat. While I have one I could use, I opted to setup a new droplet in DigitalOcean instead (I also run my own servers like you). A 2 core / 2GB RAM / 50GB SSD disk droplet on DigitalOcean is about $18 (USD) a month, while a single core droplet is about $12 (USD) per month.
If you plan to run an instance for others to use, be aware the federation is going to be chatty on your home network, and could impact other devices on your network. Probably not ideal, which is why I opted for a droplet in DigitalOcean instead.
Real devs do it in prod!
I’m seriously tempted to write some performance tests in jmeter, locust, or k6, and fire up some live traffic simulations / simulated load against my lemmy instance to see what happens. But at the same time that would feel too much like work and I don’t want to work over the weekend.
A “transfer my community” feature that allowed an entire community to be moved between instances would certainly help. That’s a great idea.
From what I’ve seen so far looking through the Postgres db, every instance has data from most other instances. I see users in my local Postgres db from other instances. So, theoretically moving a community from one instance to another could be as simple as changing a few values in the database. Of course in practice it’s never that simple. 😀
I thought about adding the gif but decided it would have been too much.
Ideally, yes. If that can be the reality, and I suppose that is how it should would with federation, then server costs should never get out of hand.
I’m running my own instance, so I’m doing my part!
You bring up a very good point. Currently lemmy.ml has thousands of users. Lemmy.world has thousands of users. The hardware they have selected to run their instances is adequate for now, but, what is the plan for scaling out if the user base grows? Is there one? They have a donation page on each lemmy instance (click or tap the heart icon,) but that can’t be enough to pay for the cost of running something used by millions of people, even if only 100s of thousands are ever only online at any given time.
In terms of UI/UX, @dessalines@lemmy.ml has mentioned in a post they are currently working on major performance improvements and enhancements.
Can we only pick one?
It certainly has! I have been on here all day… I keep telling myself to log off but here I am.
Well, it’s in the honeymoon phase right now, so everyone is cheerful, happy, and nice. All the jerks haven’t moved over yet… 😀
I still haven’t logged off! Somebody help me! Good on you for at least starting some laundry.
I’m embarrassed to say that so far my Saturday has consisted of reading and posting on various lemmy instances. Is that how is typically spend my weekend? No. I should log off.
Good luck!
Sorry about the extra duplicate posts. I’m using the mlem app on iOS and I guess it’s still a bit buggy. Time to file some bugs.
Aren’t people getting banned on Reddit for promoting lemmy?

Good question. I don’t know. Hypothetically speaking, if the parent instance of the community changes the relevant data in the database to another instance, would federation take over and automatically propagate the change? 🤷🏻♂️
Sounds like an interesting experiment at least, or a possible major bug waiting to happen.
