-

How to reproduce:
1. Create a new project
2. Enter Play Mode
3. Open the Profiler window (Window → Analysis → Profiler)
4. Change the profiling mode to Edit Mode
5. Stop the recording of the Profiler
6. Select any point in the profiled section

Expected result: Consistent performance between Editors
Actual result: Performance is slower and uses double the allocated resources

    2023 is much slower than 2022 even without profiler.
    So the degradation that's slowly eroded the editor and was somewhat slowed down is back in a big way.

    "WHEN PROFILING" is a bit of a stretch, performance degrades also when not profiling.
