    What is Default World Debug Stream in DefaultWorld Unity.Entities.FixedStepSimulationSystemGroup? It is taking up 20%-40% of the total processing time per frame and im not sure what I can do about it. I cant find anything online about it.

    This might be related to the 'Physics Debug Display'

    That components throws a bunch of primitive data to a Debug Stream.
    Though if you don't have a 
    PhysicsDebugDisplayData IComponentData
    on an Entity then it should not be doing anything.

    I'm getting the same issue, loading in about 4000 colliders in with an entity command buffer. I have the system running before the BuildPhysicsWorld too. It all loads fine but after about 10 frames the DebugStream is taking up to 5000ms!

    Any update/fix to this? I believe it may be related to the 'DebugStream' system not being correctly managed.
