title: Speeding up the npm install
body: <p>I am trying to speed up the npm install during the build process phase. My package.json has the list of packages pretty much with locked revisions in it. I've also configured the cache directory using the command </p>
  
  <pre><code>npm config set cache /var/tmp/npm-cache --global
  </code></pre>
  
  <p>However, on trying to install using <code>npm install -g --cache</code>, I find that this step isn't reducing the time to install by just loading the packages from cache as I would expect. In fact, I doubt if it's even using the local cache to look up packages first. </p>
