Continuing the discussion from Very poor performance in topics with a large number of posts : [image] This is a known issue and is slotted to be fixed in our next major release. Its a rather complex fix which will take at least a few days of work and will probably be done by @eviltrout Just …

Any progress on this issue? We have a topic with ~500 replies and it’s quite painful to scroll through.

Yes, this was addressed in Discourse 1.5.

Ah we are on 1.7 and the scroll behavior is still quite laggy. It appears to load replies in batches of 20, with a significant wait time between each batch. With 500 replies it can take minutes to scroll all the way through. Are we missing a configuration parameter that might eliminate these pauses? …

Why are you scrolling without reading? If you need to jump to the bottom, click the bottom date on the timeline at the right… or press end on your keyboard. If you need to enter the topic at the bottom, click the last post date in the topic list.

I noticed a couple of months ago that our major off-topic/spam thread was becoming slower than other threads. Yesterday a user finally complained about it. At 188.7k replies it consistently takes 4 seconds or longer to perform any navigation in the thread, while other threads take less than a second…

Ah, we did. I guess we didn’t consider that there might be consequences. We have three other threads that are longer than 10k posts at the moment, so I guess it’d be good to keep an eye on them. When auto-closing, is there any sort of thread re-creation that ties the new thread back to the old one?…

Links between topics always connect them, this has been true of Discourse since beta. So just add a link to a post pointing to the new topic.

Whats the performance impact of long threads? I have one that has escalated to 4.5K very rapidly and will keep escalating for at least 36 hours. Expecting thousands of messages, server is screaming. Will it help anything to close the thread and start a new one, a “part 2” to continue the discussio…

[image] ljpp: Will it help anything to close the thread and start a new one, a “part 2” to continue the discussion? Ping @codinghorror , @sam I would recommend keeping topics below the 10k count for now. Worth closing and doing a part2 when it reaches that point.

Performance improvements on long topics?

By default we auto-close topics that reach 10k replies. So did you bypass that default?
