The other day I was speculating about the JDK performance on the new Apple Macbook Pro with the new M1 chip when run with Rosetta 2. For me, it felt good enough when I compiled source code. IntelliJ run with Rosetta 2, however, felt sluggish. So I was curious how much better a native JDK might be. Today I measured the performance difference between a JDK run with Rosetta 2 and natively.

Apple changed its CPU architecture. Again. And all I could do is order one of their devices right after they announced it…
