## What it is
pyperformance is the official Python Performance Benchmark Suite, providing an authoritative set of real-world benchmarks for Python implementations such as CPython. It is distributed as a CLI tool on PyPI and used by projects like speed.python.org to measure and compare interpreter performance.

## Use cases
- benchmark python interpreter performance
- compare cpython versions with real-world benchmarks
- measure performance impact of a python patch
- run standardized python benchmarks from the command line
- track python performance regressions over time
- benchmark a custom python build

## When to choose
- you need authoritative, standardized benchmarks for CPython or other Python implementations
- you want to compare performance across Python versions or builds
- you contribute to CPython and need to validate performance changes

## When to avoid
- you need benchmarks tuned for PyPy specifically
- you want micro-benchmarks for a single library rather than whole-application workloads
- you need load or stress testing of web services

## Facets
- artifact type: cli-tool
- maturity: active
- function: benchmarking, developer-tools, cli
- domain: performance, developer-tools, programming-languages
- platform: python, cli, cross-platform
- tags: cpython, pypy, benchmarks, pyperf, python-implementations
