Bad performance when executing the Physics.IgnoreCollisions() method while in Play Mode
Reproduction steps:
1. Open the attached “repro_IN-90839“ project
2. Open “Assets/OutdoorsScene.unity“ Scene
3. Open the Profiler (“Window → Analysis → Profiler“)
4. In the Profiler window, enable the “Record profiling information“, enable “Clear on Play“ and enable “Deep Profile“
5. Enter the Play Mode
6. In the Game view, select “Ignore(false)“ and then “Ignore(true)“
7. Exit or pause the Play Mode
8. In the Profiler window, in the “Hierarchy” section, find and select the “Physics.IgnoreCollision()“ method
9. Check the performance cost of it
Expected result: “Physics.IgnoreCollision()“, on both the “Ignore(false)“ and the “Ignore(true)“ button press spikes, shows up to 50 ms in the “Time ms“ column
Actual result: “Physics.IgnoreCollision()“ on the “Ignore(false)“ button press spike shows around 170 ms in the “Time ms“ column while the “Ignore(true)“ button press spike shows around 400-600 ms
