Python is a high-level, interpreted programming language that is widely used in various fields such as data science, machine learning, web development, scientific computing, and more. Its arguably better to ignore the Machine Reassignment numbers. To verify you installed Java correctly, you can then simply run java -version. Here we look at raw numbers (because normalized pause-times are a bit strange) and as we can see ZGC in JDK 17 is way below its goal of sub-millisecond pause times. macOS x64 builds run stable with Rosetta 2, but there is a significant performance drop due to emulation.
