I am working on a relatively big Meteor project. This project is using flow --show-all-branches for type checking.

I am on Windows, while most of my colleagues are on Mac OS. I managed to get most things working well (sometimes slow but tolerable). For example, the build takes around 15 minutes. But I can't get flow to work at all. Trying to launch it either via meteor npm run ... or npm run ..., in both cases it takes insanely long (spending several hours on "Please wait. Server is initializing (parsed files...")), and even after that, doesn't always start. For my colleagues on Mac OS, it takes minutes or even seconds.

Are there some specifics about using flow on Windows, that I need to be aware of? Is there something I can put into .flowconfig? Or maybe, an alternative way to launch it that I could try?
