This GitHub issue is getting ignored, just as data-size related crashes in general aren’t being reported by the major site operators to GitHub. The admin of lemmy.world posted yesterday that he “talked to the devs”, but all this talk seems to be behind the scenes and no Github issue was opened about 0.18.1 performance problems or any server logs as details. This is really holding bakc Lemmy as a platform, the lack of server logs from high-activity more-data servers being shared.

Is upvote doing backend-federation activity process spawning into the queue, is that is what is slow? Are database inserts into the comment_like table on that server taking so long given the amount of rows in the table from accumulated data?

The federation performance is also showing signs of serious backend delays that the server logs would show. And adding emergency logging to the code to establish what exactly is going on with timeouts, retries, etc.
