title: Copying an s3 bucket to another bucket is too slow, how can I do it faster?
body: <p>Copying an <code>S3</code> bucket to another bucket is too slow using the following command:</p>
  
  <pre><code>aws s3 cp s3://bucket1 s3://bucket2 --recursive
  </code></pre>
  
  <p>Using <code>awscli</code>. But this is too slow. Because my <code>bucket1</code> contains too many files. Only 3,000,000 images copy in 12 hours.</p>
  
  <p>Looking for recommendations to help expedite the copy process.</p>
