Performance degrades when profiling in newer Editor versions
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
Reproducible with: 2023.1.0a20, 2023.1.0b3, 2023.2.0a2
Not reproducible with: 2020.3.45f1, 2021.3.19f1, 2022.2.7f1, 2023.1.0a19

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.
