3x bigger than advertised?

Hi! Thanks for getting lodash usable with imports.

We're currently on ember 2.17, ember-lodash 4.17.6

EDIT: tl;dr the version of broccoli-concat-analyser I was using was calculating the compressed size incorrectly. Turns out it's not 144KB, it's more like 68KB. But still much larger than ~24KB, which is what I expected.

I was checking out our addon weight (using broccoli-concat-analyser) to find some low-hanging fruit to slim down vendor.js and noticed lodash taking up more space than I expected!

lodash is showing as ~144kb uglified + compressed, but lodash.com says the Full build (~24kB gzipped).

Maybe we're doing something incorrectly here? I tried using https://github.com/kellyselden/ember-cli-tree-shaker but it didn't do much, like ~4kb savings from our production build 😢
Any help would be greatly appreciated. Even if you could quickly try a production build using broccoli-concat-analyser and let me know if lodash shows as 144kb for you as well or smaller

@sdhull are you using the latest version of broccoli-concat-analyser, that is 3.0? There was an issue with the way the compressed size was calculated, that I fixed a while ago: stefanpenner/broccoli-concat-analyser#20

Wow nice @simonihmig! I was using 2.1.0, and it was hard to believe that lodash could really be that big.

It's still larger than I expect (at ~68KB) but no longer an order of magnitude larger. Still makes me feel foolish to add it when we don't have tree-shaking yet and I only use a few lodash methods... 😐

But the vast differences in calculated size (between versions of broccoli-concat-analyser) make wonder how accurate the tool is. Should I take these numbers with a grain of salt or @simonihmig you feel confident the sizes are correctly calculated now?
