I already get rate-limited like crazy on lemmy and there are only like 60,000 users on my instance. Is each instance really just one server or are there multiple containers running across several hosts? I’m concerned that federation will mean an inconsistent user experience. Some instances many be beefy, others will be under resourced… so the average person might think Lemmy overall is slow or error-prone.
Reddit has millions of users. How the hell is this going to scale? Does anyone have any information about Lemmy’s DB and architecture?
I found this post about Reddit’s DB from 2012. Not sure if Lemmy has a similar approach to ensure speed and reliability as the user base and traffic grows.

Poorly. Lemmy will scale poorly.
I won’t be surprised if the larger instances start locking down more as a way to sustain themselves, like restricting communities or only allowing text posts.
Sometimes you have just to accommodate to the situation and keep going until it settles down. The error I think here is thinking something can’t have flaws and issues, even more if it’s not behind a corporations. And no one wants corporations.
It isn’t about accommodating to the situation, but planning for long term growth.
Right now, instances of Lemmy don’t have any way to fund server costs other than asking for donations. Outside of Wikipedia, that isn’t a sustainable business model. How is Lemmy supposed to survive if, every time a sub gains critical mass, it shuts down?
Which is part of any scaling effort, and you can’t really guess through predicting and resolving bottlenecks, it takes some serious expertise. And as far as I know, the Lemmy devs have never built a high-scale service before, and I think that is possibly the single biggest risk to the growth and success of the Lemmy project in general.
Source: that’s my job, I’ve been doing that for some of the most high-scale services in the world for about a decade. I absolutely could help, actually I’d love to, but I definitely won’t under current Lemmy leadership, for reasons: https://lemmy.world/comment/596235
How about helping Kbin?
I think Kbin is something good being built by good people, I get what they’re trying to do, but unfortunately I don’t have a lot of faith that it will turn out to be a successful project.
In terms of technical scaling, I’m puzzled that they went with an interpreted language if the goal is scale. I get that the basic usage of Kbin’s features may not require a ton of CPU-heavy operations, or a fine handling of the memory; but once it meets sufficient scale, there will have to be some scale edge-case bottlenecks where you’ll want to step out of the beaten path and get lower-level, so I’m a bit confused about why they chose a technology that will make those harder to get past rather than easier. PHP is great for rapid prototyping, but I’d argue that’s not what the vision should be here.
About community scale, I’m not expert, but they seem to really care to offer a karma system; and we’ve seen the karma-farming behavior that this has been incentivizing on Reddit. I don’t see why it would be any different here if enough people end up joining. Lemmy is intentionally not offering a karma system, and it really feels like the healthier move long-term.
I think all it would take would be for the Lemmy devs to admit that they’re in over their heads, and that their political affiliations have been a hindrance to the project, to the point that they transition the governance of it to other people. I really hope they do that. If they do soon enough, they’re so far ahead and built on so much more long-term thinking, that I think it would pretty much make Kbin kinda obsolete. I have no special information about this, so I could be wrong, and I hope for them that I am; but I can see that as a pretty likely outcome.
(That, and on the shorter-term, I wouldn’t contribute to a product I don’t use, and I can’t use it for now because my usage is 100% mobile, and the current lack of API means no native client. I wish the mobile web was better than it is as an application platform…)
Have you found that their political leanings have affected you in any way? Just curious if you have some sort of bias that’s making you think people on the left can’t produce efficient software.
It hasn’t. But letting terrible people have power affects the world in normalizing violence and hatred. It’s not about left or right, if they were American racists against Chinese people, I would have the exact same problem. I’m personally quite on the left, but without the hate.
I am living safe and not being targeted with hateful violence like the Uyghurs or North Koreans are, so this is far, far more important than what can affect me.
Sorry I don’t want to turn this into a debate but I feel like you’re being disingenious; black people are getting killed all around your country because of their skin colour, and you have private prisons that systematically exploit prison labour. How are the social, political, and cultural challenges for your country different than theirs? I live in a country the USA has deemed an autocracy, I’m not apart of the ruling class, but I am living safe and not being targeted with hateful violence. Likewise, are you ignorant to the plight of ethnic minorities in your country and the hateful violence they experience? It just seems so chauvanist of you to say that your country is superior than anothers because you have the privilege of being “safe”.
Wouldn’t that create a natural balance though? A large instance starts struggling so people are incentivised to move to smaller instances or start new instances and so spread the load more evenly. That’s how it would scale. I’m surprised how many of the larger instances haven’t closed signups yet but that wouldn’t be a bad thing if they did.
The issue isn’t on the user end, but the sub end since that is where all the data is stored.
So, according to your proposal, the best thing a sub should do when it is getting popular is to go private with its existing subscribers and any new people who want to participate should go create their own sub in a different instance.
I wasn’t talking about subs, I’m talking about when an instance gets too popular. Ideally you’d want lots of small instances, ideally communities should be spread evenly as well and if your users are spread out that should happen more or less naturally.
Where do you think the main costs of internet traffic and data are?
When the protocol favors monoliths, we’re right back to the Reddit problem
Scalability doesn’t mean “favoring monoliths”. It’s just scalability and honestly, 60k users shouldn’t bring a service down. 60k users is not even close to being a monolithic instance.
Scalability does mean favoring monoliths because it costs money to scale and scaling here isn’t proportional to your instance’s users, it’s proportional to the size of the entire network.
60k users is today, not tomorrow. I’m thinking forward to 6000k users.
