asv-runner
Core Python benchmark code for ASV
Decision gist · record as of 2026-08-14
Yes, if you are using ASV for benchmarking or building custom benchmark infrastructure. Install it as a dependency of asv or directly if you need a lightweight, zero-external-dependency benchmark runner. The active maintenance, permissive license, and broad Python version support make it reliable. No known vulnerabilities.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.7 or later; designed as a core library for ASV, not typically used standalone.
- Low install friction with a single runtime dependency (importlib-metadata).
- Active maintenance with a release 10 days old and recent commits.

What it is and what it does
asv-runner is the execution engine for the ASV benchmarking framework. It provides the core Python code that actually runs performance benchmarks, measures their execution time, and collects results. The package is intentionally minimal—it has no external dependencies beyond importlib-metadata and is designed to work across Python 3.7 and later, making it a stable foundation for benchmark infrastructure.
This is a specialized tool: it's the machinery that sits inside ASV to handle benchmark discovery, execution, and timing. Most users will encounter it indirectly through the main asv package. It's useful if you're building custom benchmarking infrastructure, extending ASV's capabilities, or need a lightweight, dependency-free benchmark runner for embedded or constrained environments.
Use it for
- Run performance benchmarks as part of continuous integration to track code speed regressions over time
- Measure and compare execution time of different implementations or algorithms in your codebase
- Build custom benchmarking tools or frameworks that need a stable, minimal-dependency benchmark executor
- Profile code performance across multiple Python versions in a single test suite

More System packages
Provides a platform-independent file locking mechanism to coordinate access to files across processes and threads.
Distro provides a reliable, machine-readable API to query the Linux or BSD distribution name, version, codename, and other OS platform details, replacing Python's deprecated `platform.linux_distribution` function.
Install it if you need to detect or report the Linux/BSD distribution your code runs on.
psutil retrieves real-time information about running processes and system resources (CPU, memory, disks, network, sensors) across multiple operating systems, enabling system monitoring, process profiling, and resource management.
Pexpect spawns and controls interactive console applications by sending input and matching output patterns, automating tasks that would otherwise require manual interaction.
Provides asynchronous file I/O operations for asyncio programs, with automatic selection of the best available backend (io_uring, libaio, thread-based, or pure Python) depending on your system.
Portalocker provides cross-platform file locking with support for exclusive and shared locks, plus Redis-based distributed locks and process-aware PID file locking.
Install it if you need file or process coordination; the optional extras (pywin32, redis) are only required for specific lock types.
