Feedback Performance degradation of BuildPhysicsWorld with Entities 0.5.0

A few day ago I switched to Entities 0.5.0. And now I came across a problem with frame by frame performance degradation.
To reproduce:

1. just put empty game object and add Physics Body and Conver To Entity components.
2. open profiler
3. run

GC.Collect is called more and more often, but I didn't find that on 0.4.0

Initial screen:


After ~30min:


My setup:

 

@Joachim_Ante Thank you for your reply.

1. I created a new empty project
2. Installed all necessary packages
3. Turned off leak detection
4. Turned off Jobs Debugger
5. Created empty GameObject on the scene
6. Added Physics Body + Convert To Entity to it
7. Run
8. Wait ~15min

Performance downgraded from 800 FPS to 150 FPS

@Yuriy_Sevastyanov Can you check your entities debugger whether it may be related to https://forum.unity.com/threads/cas...icssystem-being-recreated-excessively.811440/?

 

@florianhanke It looks like the same issue. I can see a lot of PhysicsStep

 

Thanks!

 

Is there a patch we can apply in the meantime?
