For this, in the context of the OpenJDK, we use [JMH](https://github.com/openjdk/jmh) for performance benchmarks. It avoids all the common issues with less sophisticated approaches. At first, it might seem harder to use, but it is more reliable than ad-hoc measurements. While not perfect, it has established itself as the "golden standard", so to say. ------------- PR Comment: https://git.openjdk.org/jdk/pull/17291#issuecomment-1904217509
