title: AWS S3 LISTING is slow
body: <p>I am trying to execute the following command using AWS CLI on an S3 bucket:</p>
  
  <pre><code>aws s3 ls s3://bucket name/folder_name --summarize --human-readable --recursive
  </code></pre>
  
  <p>I am trying to get the size of the folder, but given there are multiple levels and a huge number of files, it running for hours.</p>
  
  <p>Is there an efficient way to quickly get the size at folder level on Amazon S3?</p>
