pyperformance is the official benchmark suite for measuring the performance of Python interpreters. It runs a variety of workloads close to real applications and is used to track performance changes between CPython versions; the CPython development team uses it as the baseline for optimization work. It provides commands to save results as JSON and compare two results, and uses the pyperf module for stable measurements.
