Stepping physics world is taking too long

Here is a screenshot of profiler:





Having one moving capsule and a static plane in the scene makes the physics world take this long (game runs at 30FPS). is this normal?

 

Physic system runs pretty poorly in editor so you should only judge it in a build. That said I definitely get better than 30fps with just that.

 

What's the deal with these allocations and GC calls? I see in profiler that GC.Collect takes 40-70 ms of time.

 

I made a standalone build and it's infinitely faster. Running 300-500 FPS. (The whole thing takes less than 2ms).

 

Do you have stack trace on?

 

Thank you. I didn't notice I turned the stacktrace on.
Turning it off removed (almost) all GC allocations.
