My site recently updated to the latest discourse version from a much older version.
We had a thread that was standing at around 68,000 replies. People were continuing to load the thread and reply daily without any impact on the site or its servers.
It seems like after the update loading the large thread significantly slows down the site for all users. About half the time, the thread load fails with a timeout error. It also doesn’t seem to cache/paginate properly - if I try to load the most recent posts, navigate away, then load the recent posts again, I get the same long loading times and Discourse drops me in at the start of the thread.
I want to ask about what functionality was there before for pagination/caching of large threads and if anything has changed in the last 6 months or 1yr+ of updates.
