Yarn also does this very well & pioneered reconsidering how we store stuff, I believe. But they broke the universe when they switched it on by default in v2, in ways I'm not intimate with. v3 maybe possibly makes things somewhat better[1], started looking at ways to be flexible/allow different strategies. I do care about speed a good bit, as I've seen more big monorepos happen. At first I was a bit sad that Yarn v2+/pnp was beating Pnpm "with cache, with lockfile" by so much, but pnpm's "with node_modules, with lockfile" is basically the same speed. The first is more the "get started with cache" case (and what yarn v2+/pnp does every time there there-out), but the second is what most day to day dev really is: the speed converges totally in the day to day. A zoom in on the graph might reveal some differences perhaps; looks like ~2s, which is a small bar on this graph. Also pnpm is like 2x as fast if you don't have cache, so actual first install win may well go to pnpm again.
