Module load cost

Counted with a module.registerHooks load hook, compile cache disabled. Counts every JS module actually evaluated on that code path (native addons excluded). Built-ins loaded after bootstrap are counted separately, including the internal modules they load.

Install footprint and published tarball

Each version installed on its own into an empty project with nothing but @nuxt/cli as a dependency, so the tree is exactly the CLI and its transitive dependencies. npm cache is warm and the registry is only consulted for metadata, so install wall time is indicative, not a network benchmark.

Metric	baseline v4.0.0	head v4.0.1	Delta
Direct dependencies of @nuxt/cli	23	23	0.0%
Packages in the installed tree (unique name@version)	39	39	0.0%
Unique package names	39	39	0.0%
Package directories on disk (cross-check)	32	32	0.0%
Installed node_modules on disk	2.46 MB	2.46 MB	-0.0%
Installed files	436	436	0.0%
Install wall time (warm npm cache, median of 3)	1.31 s	1.30 s	-0.4%

Interleaved runs on a shared runner: trust the deltas, not the absolute timings. The dev, restart and build suites run locally via pnpm bench:cli.
