/c/[email protected] is the second biggest community on Lemmy.World and yet on /0, there is nothing newer than two days.

/c/[email protected] has two posts from today but based on the vote count, I think it’s only showing votes from this instance

    It’s more to do with the lemmy itself as a platform handles than bandwith. Basically, there is only one channel between any two instances, and it’s serial, and each step requires multiple handshakes to complete. Add in geographic distance making those handshakes take a significant part of a second to complete, and you end up with a single channel that gets flooded.

    Blahaj.zone is 1.3 million activities behind on lemmy.world for example, but we’re not behind on any other instance, because those channels don’t hit capacity. Now, if we could use multiple channels at once to talk to lemmy.world, we wouldn’t have a problem, but lemmy isn’t built for that at the moment

      Lemmy.world is really too big. We just moved [email protected] to [email protected] to try help with those issues.

      Hopefully other communities will do the same, but the issue doesn’t seem to be very well known.

      By the way, thank you for your post about centralization of communities a while back, I used it in the post to explain to the community why we were moving: https://lemmy.blahaj.zone/post/10810804?scrollToComments=true

      and you end up with a single channel that gets flooded.

      The idea behind federation was that you don’t get single instances so large that the single sync channel gets flooded. You’re meant to have more smaller instances spread out that then federate with one another like a mesh- only one copy of data needs to be sent to each instance to serve additional thousands of users without further load.

      That said, realistically the fediverse needs single instances with 10-30k users to really thrive, and L.W hasn’t even hit 10k actives… so there does need to be some batch improvements in the backend still.

      Having the ability to “merge content” from multiple instance communities would help a lot too. People congregate on L.W both from inside and outside the instance because it’s big and has the most content. But if you have multiple communities (e.g, search “memes” and see how many different memes communities there are) the others with less content get ignored. Being able to merge those from a user viewing perspective, so you would just have a “memes” group that sees federated content from all the memes communities, could reduce the need for L.W to be all encompassing.
