Debugging reselect performance

Some steps I'm taking to debug bad performance with reselect.

My performance problems are coming from the fact that I am not using reselect properly. I wrote a bunch of selectors that use props but don't do anything to make sure they can be shared across multiple components.

The fix for this is: https://github.com/reactjs/reselect/blob/fec65b63b9a2ffa570348271138d20cf831e0185/README.md#sharing-selectors-with-props-across-multiple-components.

But before rewriting tons of code, I'd like to see which selectors are recomputed the most.

// note: I'm using redux-actions in here, so the actions might look a bit different than you are used too
// note: This is not complete but the concepts are

// excerpt from app.js
import { createStore, applyMiddleware } from 'redux';
import thunk from 'redux-thunk';
import fetch from 'isomorphic-fetch'

// note: you could totally leave out the fetch argument here if you set a default (as I do in my actions)
// I'm right now not absolutely sure how I will handle this in the future (the way it is now it is a bit redundant)
