Benchmarks of JavaScript Package Managers
Last benchmarked at: Mar 15, 2026, 3:17 PM (daily updated).
This benchmark compares the performance of npm, pnpm, Yarn Classic, and Yarn PnP (check Yarn's benchmarks for any other Yarn modes that are not included here).
Here's a quick explanation of how these tests could apply to the real world:
clean install: How long it takes to run a totally fresh install: no lockfile present, no packages in the cache, nonode_modulesfolder.with cache,with lockfile,with node_modules: After the first install is done, the install command is run again.with cache,with lockfile: When a repo is fetched by a developer and installation is first run.with cache: Same as the one above, but the package manager doesn't have a lockfile to work from.with lockfile: When an installation runs on a CI server.with cache,with node_modules: The lockfile is deleted and the install command is run again.with node_modules,with lockfile: The package cache is deleted and the install command is run again.with node_modules: The package cache and the lockfile is deleted and the install command is run again.update: Updating your dependencies by changing the version in thepackage.jsonand running the install command again.
