Any search_after performance updated?

Hi. I'm using 7.10 and I'm going through exact same situation below link.

As the @mayya 's answer (Thx mayya!), I expected search_after performance has improved at 7.16, so I looked over 7.16 release note, but I can't find this update news.

I'm wondering which version I can use of performance improved search_after.

Thank you.

You are looking at the wrong release notes, these are for our Enterprise Search product.

Elasticsearch 7.16 release notes are here, and the item related to the sort optimization with after is this one:

"Add sort optimization with after from Lucene #64292"

Hooray. Thanks mayya. I'll look into the release note.
