title: Will node.js make use of multiple cores?
body: <p>I have a Ubuntu 16 machine with two Node.js web sites, ie two Node.js applications listening on different ports. If the CPU has more than one core available, will the two web sites be running their threads on different cores? Is there anything I must do to make them always run on separate cores?</p>
  
  <p>Curently, I launched my applications simply using:</p>
  
  <pre><code>cd app1
  nodejs ./server.js
  cd ../app2
  nodejs ./server.js
  </code></pre>
