I noticed something that I’m hoping someone could clarify.
When I visit lemmy.ca, and show “all” communities and then compare it to lemmy.world, the results come up totally different… different posts or same posts with wildly different number of comments.
It doesn’t seem to matter which sorting method I use, either.
Even replies to a comment within a post will have more on lemmy.world than if I were viewing it on lemmy.ca.
For example, !nostupidquestions on lemmy.world shows the post “Do you think the guys on the titanic submarine will be rescued?” with 589 upvotes and 474 comments. The same post shows 167 upvotes and 384 comments on lemmy.ca.
I checked the blocked instances between the two, and only junk instances are there, so I know it’s not that.
Any clarity would be appreciated.
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.
