SequenceAssetIndexer.InitializeWithExistingData adds overhead when entering Play Mode in a heavy project

Package: Sequences

-

Reproduction Steps:
# Open the attached project
# Enter Play Mode
# Observe delayCall callbacks locking up for a few seconds right after the initial application reload

 

Expected result: there is no significant overhead from Sequences-related code when entering the play mode

Actual result: SequenceAssetIndexer.InitializeWithExistingData subscribed to EditorApplication.delayCall results in several seconds of added overhead because it's loading objects.

Editor versions tested: 2020.3.0f1 (first available), 2022.2.0a1, 2023.1.0a1, 2023.1.0a26

 

Tested using a 2019 MacBook Pro 16" i9/32GB

    Duplicate issue. This one was hiding in the backlog so I missed that it was the same thing. Solution in progress.

    It seems linked to the number of timelines in the project. With near 1000 timelines I have a 27 seconds overhead when entering play mode and at every domain reload.
    I’ve created 256 empty timelines and it added 14 seconds of overhead
