Slow in Unity 2019.3.11f1?

Since updating from Unity 2019.2 to Unity 2019.3.11f1 I noticed the game seems to run a lot slower. Profiling the editor and play mode A* Pathfinding project has jumped up to the slowest element in the list.

In the editor, the Cut Poly work item is high on the list, although this shouldn’t be running in the editor at all

Similar profiling result in play mode, same scene
