I started a private instance today, and maybe I’m being impatient but I’d like to know if there’s something I can do on my end to keep my instance more closely in sync with the remote communities I’ve subscribed to. I don’t seem to be missing any new posts, but there are so many missing comments which makes the sort options (Active, Hot) bring up posts that sometimes are weeks old. Are there any configuration options or tuning options that could help my instance “keep up”?
Nothing you can do about it on your end. ActivityPub seems to require the larger instances to send outbound notifications, messages received more than 10 seconds old are tossed out, and it appears right now the larger instances can’t keep up with delivery in that time frame. Makes sense… lemmy.world instance has 3.6K users and 2200+ federated servers. If only 10% of the users upvote one post, that’s over 700K out going notifications already. I’d imagine a larger portion of the current users being more active considering large chunk of us are the more active Redditors seeking refuge…
Oh boy, I wasn’t really aware of the numbers, but yeah, I wonder how this should be handled to scale.
Active and Hot are kinda weird right now, they’re fixed in the next version, but your best way of seeing trending stuff currently is by doing Top Day/Top Week.
Some of the bigger communicaties like Lemmy.world and lemmy.ml are experiencing terrible growing pains from the massive expansion of Lemmy. You can help your own instance by adding more federation workers in the admin panel, assuming your hardware is up to the task, but I think a lot of the missing comments are a factor of the big communities being overloaded.
Increasing my federation workers to 1500 resolved a lot of my warnings in my logs, but I’m still missing tons of comments from Lemmy.world.
There is an Open Issue on Github
