    <desc>The amount of CPU being used tells you how much work the computer is trying to do.</desc>
  </info>

  <title>Check how much processor (CPU) capacity is being used</title>
  
  <p>To check how much of your computer's processor is currently being used, go to the <gui>Resources</gui> tab and look at the <gui>CPU History</gui> chart. This tells you how much work the computer is currently doing.</p>
  
  <p>Many computers have more than one processor (sometimes called <em>multi-core</em> systems). Each processor is shown separately on the chart. If you want, you can change the color used for each processor by clicking one of the colored blocks below the chart.</p>
  
  <p>You can also change how rapidly the chart is updated (the update interval), and how the lines for each processor are displayed (e.g. as a stacked area chart). Change the relevant options by clicking <gui>System Monitor</gui>, then select <gui>Preferences</gui>, and then the <gui>Resources</gui> tab.</p>
