That actually sounds like something I would have enjoyed. I joined Reddit around the time it started taking over, I think.

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.
I really hope someone is doing some level of performance testing on those changes to make sure the changes fix the performance issues.
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.
Oh, Big-O notation? I never thought I’d see someone else mention big O notation out in the wild!
:high-five:
I did see it, thanks. I’m hoping to find some time to contribute this week.
Welcome here, and thanks for creating the CR community.
Is it Thursday yet?
I suppose I could, but, I've honestly spent the majority of today on lemmy answering "support" questions for people lol... Maybe I can try to take a look tomorrow. 🤷
Actually, saving edits on lemmy.ml is also slow, about 4-5 seconds. It’s probably a combination of user load and non-optimized queries.
Would be funny if it was missing an index and doing a full table scan for some odd reason...
I focus on application performance in my day-to-day work, and missing indexes, greedy upoptimized queries, etc, are the root of a lot of issues. Hopefully you can get to the bottom of it.
Quick note: I'm not seeing a big delay (10+ seconds) when posting or saving on lemmy.ml, or my own instance.
OMG! You are right. It’s my time to shine!
This sounds like a bug…

Yes. Absolutely does happen on other instances that have thousands of users.
