I'm playing around with Unity DOTS and am trying to do some raycasting but I'm getting abysmal results. I tried following the examples here and here (My code is identical to the first link). I decided to compare PhysX, Unity.Physics and Unity.Physics with Jobs+Burst and run 10,000 raycasts. My results were. PhysX: 6ms Unity Physics: 70ms Unity Physics (Jobs and Burst): 350ms Normally I get pretty great results with Jobs and Burst so I'm not entirely sure what I'm doing wrong. When I look at the Profiler the script running the above is taking up the whole process. When I look at the Entity Debugger I noticed BuildPhysicsWorld and ExportPhysicsWorld is taking up the most time, especially when using Unity Physics with Jobs+Burst.
