Apple macOS 10.15 vs. Windows 10 vs. Ubuntu 19.10 Performance Benchmarks
When running NAMD across the three operating systems, Ubuntu 19.10 did deliver the best performance.
Ubuntu 19.10 also delivered the best Golang performance aside from the JSON parsing test where macOS Catalina was the victor.
Running some Java language micro-benchmarks also allowed Ubuntu to rack up some more wins.
In the Java-written DaCapo and Renaissance benchmarks, Ubuntu 19.10 was generally the front-runner here as well with all these tests on OpenJDK 11.
