I am curious what % of user can the current lemmy instances take in from reddit

Can fediverse take on 30%, 50% or 100%?

For start, what are lemmy.ml and lemmy.world doing, are they just keep scaling up?

I think the current hardware for Lemmy.world should handle maybe 1M users, if the Lemmy software is tuned. If it should grow more, we need to look into horizontal scaling with Kubernetes.

But hopefully there will be more and more servers so the users can be spread more.

Thanks for hosting Lemmy.world! Does Lemmy use a database? Until the software gets horizontal scaling capability, could we use a central RDS so the load isn't on the EC2 instance's CPU? Then we can use load balancing between multiple instances that pull from the same DB? Obviously, the db instance is still a limiting factor.

It all runs on 1 physical server in docker containers. Scaling the Postgres database is least of my worries (I am a DBA) :-)

Ah, you know more than me then lol. Keep up the great work, glad to be a supporter!

Will there be a user count# at which you close registering and encourage new users to different feds?

Is 1m users total registered, or synchronously active?

How can one donate to server upkeep, and what is your stance on financial transparency?

[–] ruud 14 points 1 year ago

Donation links are on the front page. Finances are at https://blog.mastodon.world and will be posted here when blogged.

Out of curiosity, what's the current hardware?

How are you paying for this? Is lemmy.world controlled by you as a private individual? Is this going to be transferred to some sort of non-profit, or business entity? What are the options where you are at? Have you considered the legal aspects of various locations, (e.g. free speech protections, reach of law enforcement, etc)? Since this has the potential to blow up, now is the time to start thinking about these things?

[–] ruud 17 points 1 year ago (2 children)

That's a lot of questions :-) Quick answers:

  • It's being paid by donations (see homepage for links)
  • It's owned by me and run by a team of sysadmins/mods
  • I might think of a non-profit for all my Fediverse servers one day. For now I'm using my BV (dutch company).
  • Still looking into the legal stuff, also for Mastodon. Working with https://about.iftas.org

Sorry if you already know this, but this might be helpful for lurkers that don't know such a thing exists.

I don't know anything about dutch corporate structures, but some US states have an entity called a benefit corporation. Think of it like a non-profit and corporation hybrid. It allows you to make a profit and grow, but operate like a non-profit where the purpose of the organization is something else. This gives you more flexibility that might not be available as a non-profit. I believe you can even incorporate as a non-citizen (I'm assuming here). Might I suggest an ask lemmy post to get ideas?

[–] ruud 6 points 1 year ago

Yeah I will, in due time. For now focussing on other stuff. But it's on the roadmap.

[–] Toylerrr 2 points 1 year ago

How do you feel about all this commotion? Do you think the "great migration" might actually happen?

[–] V4uban 3 points 1 year ago

Interesting, thanks for the insight

[–] pca006132 2 points 1 year ago

Wondering what is the bottleneck for the system. Number of requests per second or something?

[–] TragicNotCute 26 points 1 year ago (1 children)

Lemmy.world recently bought a brand new dedicated server to scale with the load. All the way to the moon baby!

Do you happen to have the link to this announcement?
