It's still not /great/. I have had to switch from my mac to a new Win10 laptop for development because the app server in my docker container would take around 2 mins to detect a change and reboot the app server, which then would take a few minutes to reboot. Now it's much closer to realtime. I do hope that docker get's it sorted out soon, as the tooling on windows isn't as good as what I am used to on osx.

And by tooling, I mean command line. I am using Cmder with Linux subsystem for Windows, and it STILL isn't half as good as even the terminal built into osx, let alone iterm.
