If you drag’n drop the cursor on the timeline, it will scroll to the post, but won’t update the timeline cursor until you scroll again manually:

This is because

@tgxworld

Jumping to an index on the timeline becomes jumping to the closest post number on the timeline

@Canapin

Weirdly, even by increasing this setting to 15000, the timeline cursor doesn’t show the date on a 10000 posts thread

We remove a lot of features on mega topics to preserve performance. Our general recommendation is The MEGATOPIC: public good, or public menace?

@codinghorror

Yes, server load gets exponentially higher with large topics. We put in some basic mitigations (you’ll note that dates don’t appear on the timeline, etc) but it’s still expensive.

@sam

The number of megatopics in the wild is minuscule, investing large amount of time optimising this means we have less time working on features which are much more commonly needed.
