Source
pnpm: Is pnpm faster than npm?

Yes. pnpm performs installation in three stages: dependency resolution, directory structure calculation, and linking. Packages are fetched and linked as soon as possible, making it significantly faster than npm's sequential approach.

Source

Source
pnpm: Does pnpm support monorepos?

Yes. pnpm has built-in support for monorepositories. You can create a workspace using pnpm-workspace.yaml to unite multiple projects in a single repository.

Source
pnpm: How does pnpm handle node_modules differently than npm?

pnpm uses symlinks to add only direct dependencies to node_modules root, preventing accidental access to undeclared dependencies. This encourages more explicit dependency management compared to npm's flattened node_modules structure.
