MERN : Slow start/restart

Hey, I've started using (and loving) MERN stack on a new app that I've been tasked with developing, have been focussing mostly on front end up until today and it has been great!. It's currently taking 2-3 minutes to start or restart the nodemon task (via npm run start) which is pretty frustrating while I'm trying to get authentication right and having to constantly wait..

Is this a normal experience or something particular in my env??

I'm on a 2014 macbook air running Sierra and havent experienced issues with gulp, grunt or nodemon in the past, this is my first experience with webpack and isomorphic though...

-edit-

It may be worth noting that I get the child processes triggering on every change, example below:
