BuildPipelineInterfaces causes slow EnterPlaymode performance when there are many cs files in the project
Reproduction Steps:
1. Import attached project.
2. Create new scene.
3. In Profiler, select Record and Profile Editor.
4. Enter Play mode.
5. Stop recording in Profiler.
6. In Profiler Overview, find:
EnterPlaymode -> Application.WaitForAsyncOperationToComplete -> Preload Single Step -> Application.LoadLevelAsync Integrate -> BuildPipelineIntefaces.InitializeBuildCallbacks()
7. Observe Time ms.
Expected result: BuildPipelineIntefaces.InitializeBuildCallbacks() should not make a new scene this slow.
Actual result: BuildPipelineIntefaces.InitializeBuildCallbacks() slows down Play mode. Time ms becomes much shorter only when all cs files are deleted.
Reproducible with: 5.6.2p3, 2017.1.0p1, 2017.2.0b3, 2017.3.0a1
Not reproducible with: 5.5.4f1
---------------------------------------------------
Already fixed in: 2018.1.0b10, 2017.2.0p1, 2017.1.2p2. Fixes on other versions will appear a little later
