title: What is the largest filesize supported by VS Code syntax highlighting?
body: <p>VS Code provides syntax highlighting automatically for xml and json files out-of-the-box. But when you start to process file that is larger than a certain size, the syntax highlighting no longer works. </p>
  
  <p>Many other features might be disabled as well. </p>
  
  <p>For example, </p>
  
  <ul>
  <li>Open a json/xml file less than 10MB, everything is normal. </li>
  <li>Open a json/xml file larger than 40MB, syntax highlighting does not work. </li>
  </ul>
  
  <p>What is the root cause for this, and what is the exact limit of file size for these capabilities to work?</p>
