 I started off with a small repo of mine, `nolanlawson/tiny-queue`, then moved on to some popular libraries like `lodash/lodash` and `facebook/react`. In each case, I'm just cloning the code from Github and running `npm install`.
 
 **TLDR:** Regular npm is faster for the first `npm install`, but afterwards `local-npm` is always faster, even after `npm cache clear`. Sometimes it's even 2x or 3x faster (e.g. 1m15.752s vs 3m50.467s to install `facebook/react` the 2nd time). This is kind of the point of `local-npm`: it gets faster the more you run it, because it aggressively caches everything.

+# Notes
 
 The test is a little unfair, because my `local-npm` has already downloaded all the metadata, but this is a typical use-case for `local-npm`. (It replicates the npm metadata on first run, which can take a few hours.) I did clear out the tarballs before the test, though.
 
 Also, repos tested later in the test may benefit from a slight boost, if they share any modules with a previous repo. But again, this is a typical use-case for `local-npm` &ndash; the more you use it, the more that common tarballs will be pre-cached.
 
 I find it interesting that `local-npm` is faster even after the second `npm install`, which is when npm's cache is supposed to kick in. This suggests that npm is not caching as aggressively as it could be.

 First, `npm install -g local-npm && local-npm`. Then just clone this repo and run `npm test`. The python script can print a summary afterwards.
 
-**Warning:** the test will override your local `~/.npmrc` file! So you may want to do `npmrc -c testing && npmrc testing` beforehand.
