Jest is 3x slower on all windows machines (Windows 10 and lower)

## 🐛 Bug Report Jest is slow on windows machines. ## To Reproduce Anyone with a windows desktop machine. ## Expected behavior It should be lightning fast. ## Run `npx envinfo --preset jest` Paste the results here: ```bash System: OS: Windows 10 CPU: (4) x64 Intel(R) Core(TM) i5-7400 CPU @ 3.00GHz Binaries: npm: 6.2.0 - C:\Program Files\nodejs\npm.CMD ``` I've done a ton of reading around and it seems like 100% of all windows users are being affected by delaying in running tests with jest, while it is blazingly fast for all mac users. Has there been any research or attempts to find what is causing this? Currently I'm copy and pasting all of my components and unit testing them in codesandbox, (It instantly runs tests blazingly fast) then copy and pasting them back into my project, which isn't the most ideal way to do it but I love the API that jest offers.
