Wants the point of a decentralised platform if most of it’s users are on a single instance.
It's so that users have a choice of joining different instances. If .world is particularly well managed and provides amenities for users and has the capacity, there's no reason that new users shouldn't join.
The junk communities in every instance are a problem.
As I understand it, Lemmy.world's maintainer wants to own the biggest Lemmy server ever, just like they own one of the biggest Mastodon servers. It's a feature, not a bug.
I wish lemmy.ml (also unstable) or lemmy.world would hand out a (nearly) full copy of the database so we can get more analysis done on PostgreSQL performance behaviors. Remove the private comments and password /2fa/user, or whitelist only comments/posts/communities/person tables - but most everything else should already be public information that's shared via the API or federation anyway. it's the quantity, grouping, and the age of the data that's hard to reproduce in testing. And knowledge of other federated servers, even data that may have been generated by older versions of Lemmy that new versions can't reproduce.
It's been over 60 days of constant PostgreSQL overload problems and last week Lemmy.ca made a clone of their database to study offline with AUTO_EXPLAIN which surfaced a major overload on new comments and posts related to site_aggregates counting (it was counting each new post/comment against every known server, not just the single database row for a server).
I have an account over on World too, and every major Lemmy server I use throws errors with casual usage. It's been discouraging, I haven't visited a website with this many errors in years. Today (Sunday) has actually been better than yesterday, but I do not see many new postings being created on lemmy.ml today.
subscribe to every community, and let federation load overwhelm your server.
Did that, takes lots of time to wait for the content to come in.... and there is no backfill. Plus I suspect that the oldest servers (online for several years) have some migration/upgrade related data that isn't being accounted for.
I don't think you understand how the fediverse works of you think that solves the problem - lemmy.world being unstable effects its ability to federate properly with other instances
Badly managed popular instances unfortunately affects the whole fediverse
There has also been problems with federated copies of communities not getting all the actions. I added testing code to demonstrate that comment deletes were not going out to federation peers. Comparing copies of data between instances for the same community shows some overlooked problems. Still have more tests to add.
Lemmy.world is a great landing page for people migrating from Reddit.
I think the main reason people gravitate towards the biggest instance is FOMO, but the whole philosophy behind federated networking will hopefully promote people to move elsewhere, or make their own, once everyone is more familiarized with how it works.
No, I'm trying to find a solution to a very real problem. World has had at least partial outages every day for a week now. It affects everyone when it gives the impression that things don't work and people aren't able to create content to attract new people to the wider platform. But have an upvote anyway.
People can subscribe to other instances or even host their own. If the majority of users end up on the same instance then what's the point of decentralization? Even worse if the traffic it generates for that instance makes it unstable.
Should the admin do nothing until the instance is mostly down with windows of uptime throughout the day?
A big part of the problem is that a new instance starts with zero database content and PostgreSQL performs fine with the way Lemmy organizes the data. But then there isn't anything for people to read, and search is only going to pick up local stuff.
