Large workspace installation slow on Windows

[Methuselah96]

I've been looking into switching from Yarn PnP to pnpm for a large workspace I have at work. I assumed that the installation time of Yarn PnP and pnpm would be fairly close, since that's what the pnpm benchmarks seem to suggest. However, when benchmarking the installation times on our work project, specifically on Windows, pnpm was noticeably slower than Yarn PnP.

I forked pnpm's benchmark tool, and added a new fixture that matches the workspace layout our large workspace. Here are the results I'm currently getting:

Windows

action	cache	lockfile	node_modules	npm	pnpm	Yarn	Yarn PnP
install				1m 31.4s	41.3s	38.4s	17.3s
install	✔	✔	✔	3.8s	2.6s	3.3s	n/a
install	✔	✔		39.5s	18.4s	23.9s	2.7s
install	✔			55.8s	29.1s	27.7s	5.7s
install		✔		45.5s	31.9s	33.6s	13.1s
install	✔		✔	4.3s	7.6s	6.5s	n/a
install		✔	✔	4.6s	2.6s	13.2s	n/a
install			✔	4.3s	26.5s	16s	n/a

Linux

action	cache	lockfile	node_modules	npm	pnpm	Yarn	Yarn PnP
install				1m 9.6s	20.2s	26.6s	14.3s
install	✔	✔	✔	3.3s	1.8s	2.6s	n/a
install	✔	✔		18.7s	5.2s	14.5s	2.2s
install	✔			30.2s	14.3s	18.1s	5.1s
install		✔		24.3s	11.1s	22.6s	10.1s
install	✔		✔	3s	6.9s	5.3s	n/a
install		✔	✔	3.1s	1.9s	10.8s	n/a
install			✔	3s	13.3s	14s	n/a

I'm assuming based on the fact that Windows is much slower than Linux, that the slow installation time is due to Windows file system operations being slow.

Has anyone else experienced this? Is there anything that can be done to make the package installation faster on Windows?
