  <title>Que é a memoria de «intercambio»?</title>

  <p>Swap memory or <em>swap space</em> is the on-disk component of the virtual
  memory system. It is pre-configured as a <em>swap partition</em> or a
  <em>swap file</em> when Linux is first installed, but can also be added
  later.</p>

  <note>
    <p>Disk access is <em>very</em> slow compared to memory access. The system
    runs more slowly if there is excessive swapping, or <em>thrashing</em>,
    when the system is unable to find enough free memory. In this situation the
    only solution is to add more RAM.</p>
  </note>

  <p>To see whether swapping, or <em>paging</em>, has become a performance
  issue:</p>
