We’re still working to find a solution for the posting slowness in large communities.
We have seen that a post does get submitted right away, but yet the page keeps ‘spinning’
So right after you clicked ‘Post’ or ‘Reply’ you can refresh the page and the post should be there.
(But maybe to be sure you could copy the contents of your post first, so you can paste again if anything would go wrong…)
@ruud@lemmy.world Yo dude, first off huge props and a big thank you for what you have setup. I’ll be donating monthly while I am here. I appreciate that we have an alternative to Reddit at this critical moment in time.
I do have a question on your long term plans, do you want to continue to expand and upgrade the server, as funding allows, or is there a cap that you will close off the server to new members? Or perhaps make it more of a process to join?
Well if all the Reddit users would get over to Lemmy I guess all servers would need to scale up… but I think the server we have now is powerfull enough to grow quite a lot, as long as the software gets tuned …
Agreed. Exp Full stack Web dev here. This slowness is clearly a dev issue. The “it keeps spinning” is rarely a db issue or server issue IF the server has power and this one has. This smells to much like something is timing out . I also noticed that when I reply to someone who was logged in from kbin (or even mastodon) it just never ever submits.
I’m not that familiar with federation itself. But I do know my way around the web. I too hope that they fix this asap. It could even be something like a non sorted query. Or just an endless/to long loop. These are the most typical bugs that happen when there is more data.
Anyway just my 2 cents. Like I said I’m not that familiar with the Lemmy code.

Just hopping into the chain to say that I appreciate you and all of your hard work! This place—Lemmy in general, but specifically this instance—has been so welcoming and uplifting. Thank you!
I assume that there is something that is O(N), which explains why wait time scales with community size (amount of posts, comments)
Oh, Big-O notation? I never thought I’d see someone else mention big O notation out in the wild!
:high-five:
you are going to meet a lot of OG redditors in the next few weeks. Old reddit had Big O in every post, even posts with cute animals.
maybe related, but I’ve noticed that upvoting/downvoting has similar lag delays
Same. It would be good to fix this
Is the slowdown that it the instance has to send out updates about the comment to every other instance before returning a successful response? If so, is anyone working on moving this to an async queue?
Sending out updates seems like something that’s fine being eventually consistent
Ooh that’s a good remark ! I’ll see if that’s the cause
Reading more about how this works, sending out updates to each instance shouldn’t block the request from returning unless you have a config flag set to debug source.
It might be due to poorly optimized database queries. Check out this issue for more info. Sounds like there are problems with updating the rank of posts and probably comments too
So it looks like YOU SOLVED THE ISSUE with this reply! This led me to check the debug mode, and it was on! It turned that on when I just sterted the server and federation had issues…
We no longer seem to have the slowness!!
That’s awesome! Thanks for hosting the server!
Good to know it isn’t just me then.
Been noticing this in the app I’m working on. Pretty much all POST requests fail to return a response and just timeout after 60 seconds. A quick refresh shows that the new items do successfully get created though.
Does this behaviour appear on other big instances? E.g. lemmy.ml?
Yes. Absolutely does happen on other instances that have thousands of users.
I’ve done this twice in the last 20 minutes and the content is not there. This workaround was working earlier today though.
I noticed this, thanks for the clarification
Again, thank you for the outstanding work! You are awesome!
Also, the new icon for lemmy world is great!
ok, so it’s not just me. Hope it gets resolved soon!
My comments seem to not go through sometimes, whenever I upvote posts on Jerboa I get an error that just says timeout. Doesn’t seem to happen on other instances.
Yea I started just using my clipboard alot, and hitting the x or back on jerboa and comments go thru at about 90% success rate. For posts I let it do its thing just incase. But been copying stuff to save as draft.
its def more hung up today, oddly its only first level replies for some reason
