There is a bug report on this, a quick summary is they aren't quite sure what is causing it as of yet. It could be overloaded servers, network issues, or a bug in the software. The developers are aware of it and I assume it's a problem being worked on, or already fixed for the upcoming 0.18 release.
Cool, so I won't need to create a separate lemmy.world account to see more content? I was afraid I might have to.
The intended behavior is each instance will have the same content (minus banned users/instances), so once this bug is resolved you should be able to use your lemmy.ca account only.
Right now to get around this bug, it might be good to visit discussions/communities you are interested in directly on their instance as to not miss anything. Personally, this only seems to be happening with discussions on larger instances but this is anecdotal evidence at best.
I'm not too worried if it's a bug. I was just surprised to see such a vast difference between the two instances.
I appreciate the info, and I'm looking forward to a bright future on Lemmy =)
as others of said, pretty sure it's an issue with the bigger instances struggling with the load, and/or software issues. similar to why it doesn't always work subscribing to lemmy.ml/lemmy.world communities from here. i don't think the federation from both of those places are working 100% either.
Any chance you know what percentage of your bandwidth is directly serving content to users, and what percentage is communications between lemmy.ca and the other federated instances? Like, how much bandwidth is spent just synchronizing?
that's tough to say. but i would say the communications between instances would be fairly low, because it's only text that's being transferred. no media is being sent.
What happens with embedded images? Are they pulled from the source server directly? For example, if you're federating lemmynsfw which is almost entirely images, are you caching local copies?
pulling directly from the other instance. i don't believe anything is cached to the instance you're retrieving it from.
I've also had this issue. Sometimes it seems like comments are missing or upvotes are behind. I decided to make an account on .world as well and have mirrored all my communities. I will bounce back and forth for now as it gets worked out. Sounds like it's a bug from the comments here.
Not too worried about it though. Chalk it up to growing pains.
Could defederation have something to do with it?
I believe beehaw defederated from sh.it.just.works and Lemmy.world so on lemmy.world you won't see any posts or comments from people on beehaw I believe.
I suspect it's partially to do with the Activitypub protocol itself, at least how it's implemented by Mastodon, which most other software treat as the de-facto standard. Someone brought this up to Eugen on Mastodon where the guy was showing the different amount of boosts and what not. I remember it being different on every server the guy showed screenshots from, on the same post.
Wish I could find the thread, but Eugen basically said it's not a big concern to him and didn't sound like it would be fixed.
