title: npm is really slow while installing/updating packages from private git repositories
body: <p>I use a lot of private node packages (stored on my personal github repositories) in my projects:</p>
  <pre><code>&quot;devDependencies&quot;: {
    ...
    &quot;my-package&quot;: &quot;github:username/my-package#master&quot;
    ...
  }
  </code></pre>
  <p>my issues is that, when updating a project or when running <code>npm install</code>, the process takes so long (~ 2 mins), while it's stuck doing something like:</p>
  <pre><code>reify:my-package: timing reify:loadBundles Completed in 0ms
  </code></pre>
  <p>Is there anything I can do to speed up the processes when using private repos?</p>
  <p>Thanks</p>
