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…)
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.
That’s pretty neat! I’ve honestly never seen it mentioned on Reddit before, so got a bit excited to see someone mention it here, admittedly maybe too excited.
there was a time, before the digg invasion, where someone would post a picture of a woman feeding 30 cats and there would be Big O jokes about how well this would work and crazy modifications to the situation to improve it. This would be almost every thread at one point on the site. I miss it.
That actually sounds like something I would have enjoyed. I joined Reddit around the time it started taking over, I think.
Those years before the Digg invasion are often the magic and mythic times OGs speak of, lots of amazing happened after too, but that early culture was almost entirely washed away by Digg and subsequent mainstreaming of some subs. the move from being a focus on quality link aggregation to a points game really helped push things down hill.
At this point I’m not sure meta-moderation is really a workable system and I kind of hate internet points. There are some new tools and techniques we can try in a system like this.
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!
Does this behaviour appear on other big instances? E.g. lemmy.ml?
Yes. Absolutely does happen on other instances that have thousands of users.
Great, so it’s reproducible and Lemmy-the-app related, not instance-specific. Should be fixable across the board once it’s identified and resolved.
Yes it does, tried this workaround before.
Have you tried enabling the slow query logs @ruud@lemmy.world? I went through that exercise yesterday to try to find the root cause but my instance doesn’t have enough load to reproduce the conditions, and my day job prevents me from devoting much time to writing a load test to simulate the load.
I did see several queries taking longer than 500ms (up to 2000ms) but they did not appear related to saving posts or comments.
These things are taking 15-20 seconds though.
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.
ok, so it’s not just me. Hope it gets resolved soon!
its def more hung up today, oddly its only first level replies for some reason
I noticed this, thanks for the clarification
I’ve done this twice in the last 20 minutes and the content is not there. This workaround was working earlier today though.
maybe related, but I’ve noticed that upvoting/downvoting has similar lag delays
I can’t up/down vote at all.
Same. It would be good to fix this
Thank you for your hard work and keeping us up to date.
Thank you so much
I noticed that too, page keeps spinning but comments are posted immediately anyway.
Again, thank you for the outstanding work! You are awesome!
Also, the new icon for lemmy world is great!
This is the biggest issue I have run into. Thanks for looking into it.
