A shared cache instead of copying packages** npm and Yarn copy every dependency into the project's `node_modules`. pnpm stores packages **once, in a global store**, and creates **hard links** in `node_modules`. As a result: - no repeat downloads - no multiple copies of the same libraries - fewer I/O operations, higher speed --- ### **2. Less disk work** The disk is the slowest part of installing dependencies. pnpm: - **cuts disk writes sharply** - finishes `install` faster, especially on large projects npm and Yarn spend significantly more time copying files. --- ### **3. Fast repeat installs** Since packages are already in the cache, a repeat `pnpm install` runs very fast, sometimes several times faster than npm and Yarn. --- ### **4. A strict, predictable node_modules structure** pnpm has a strict dependency structure, closer to the real semantic module graph, which: - simplifies computation - speeds up dependency resolution - lowers the chance of conflicts --- ### **Summary** pnpm is faster than npm and Yarn because: | Reason | Effect | |---|---| | Hard links instead of copies | less I/O, higher speed | | A shared cache | repeat installs are almost instant | | Fewer write operations | saves time on large projects | | A strict dependency structure | less computational overhead | This makes pnpm **the most performant package manager** of the three: npm to Yarn to pnpm.For the reviewerNote to the moderator (optional)Visible only to the moderator.
