title: Fastest way to get Google Storage bucket size?
body: <p>I'm currently doing this, but it's VERY slow since I have several terabytes of data in the bucket:</p>
  
  <pre><code>gsutil du -sh gs://my-bucket-1/
  </code></pre>
  
  <p>And the same for a sub-folder:</p>
  
  <pre><code>gsutil du -sh gs://my-bucket-1/folder
  </code></pre>
  
  <p>Is it possible to somehow obtain the total size of a complete bucket (or a sub-folder) elsewhere or in some other fashion which is much faster?</p>
