title: How much memory does a VNC server use?
body: <p>I have a <code>VNC server</code> started on my linux machine. How much memory does a VNC server use? </p>
  
  <p>If I create multiple <code>VNC servers</code> on same machine and do not use few of them for long time. Being an unused process, does operating system shift them to heap area and free the memory? </p>
