Compilation on 2020 Mac mini with M1 chip (16 GB RAM) : 11.6 Seconds
Compilation on 2016 macbook (1.2GHz Dual-Core Intel Core m5, 8 GB RAM): 2.3 Seconds
Compilation time is measured by UnityEditor.Compilation.CompilationPipeline events.
Unity version on both machines are 2019.4.15f1

I understand that Unity Editor is not running natively on Apple Silicon, and running on Rosetta2 might slow things down a little. But why is the compilation almost 5 times slower?
