At MongoDB World last week, we announced that faster counts are now available with sharded collections.
We also announced a feature called Stored Source Fields which help you achieve faster post-aggregation performance. You can use this feature to experience faster sorting with Atlas Search.
You can read more about these two ( https://www.mongodb.com/blog/post/new-ways-deliver-excellent-search-experiences-atlas-search ) features ( https://www.mongodb.com/blog/post/new-ways-deliver-excellent-search-experiences-atlas-search ) here.

After trying Stored Source Fields, if it does not meet your performance requirements - please vote on this new feedback ( https://feedback.mongodb.com/forums/924868-atlas-search/suggestions/45316366-faster-sorting-with-atlas-search ) item.
