Workaround for the performance issue with posting in large communities (self.lemmyworld)

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..)

Have you tried enabling the slow query logs @[email protected]? 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.
