I have the same issue, I tried even importing just this package into an empty project and I have the same problem in a the Third Person Controller demo scene. In my other scenes I don't have this problem it seems something specific to the character controller demo scene setup, I even tried removing everything in the scene except the camera, Nolan and the floor he's standing on and still have this frame rate problem. It's showing excessive use of EditorLoop but I don't have anything else imported into this project, just the Third Person Controller and demo scene. I also tried deleting my library and temp files and reimporting everything, it's still an issue in the demo scene and not my other scenes without third person controller. I did recently try updating to 2019.3 with the new input system and DOTS then downgraded my project and reset everything back to 2019.2.3f1 but it's possible something with the new input or rendering system is messing with the components? Thanks! I'm excited to use your controller!
