title: Why git log --cherry-pick is so slow?
body: <p>I want to get the changes between two given tags, the command is:</p>
  
  <pre><code>git log `Tag1...Tag2 --cherry-pick  --no-merges --right-only
  </code></pre>
  
  <p>but it is very slow. </p>
  
  <p>I test parameters respectively one by one. ONLY when with <code>--cherry-pick</code>, git log is very slow.</p>
  
  <p>Why? Anybody could help me out there?</p>
