For some reason, installation is very very slow on Windows, even compared to other package managers--orogene will often be slower than NPM, not to mention pnpm, which is about twice as fast.

This is even true when using DevDrive and reflinks instead of full file copies. Something weird is going on here and I don't know what.

Fixing this probably entails getting dtrace working on Windows and generating flamegraphs to see what's taking up all that time...
