Doing partial prod builds under controlled conditions for comparison purposes. Cold caches, no shrinkwrap, 3 different package.json in a monorepo-type thing, 1797 dependencies installed, only npm install times shown:

- npm4: 406.01 seconds
- npm5: 60.96 seconds

This is a bit less speedup than what I got excited about yesterday, but still (a bit) more than 6 times faster! 🎆 🍻 ✨
