title: Can I limit the CPU usage of a website for testing?
body: <p>We have developed a website that has quite a lot of flash in it and it seems to be hanging on some machines using firefox, these machines are a lower spec than our development machines and we cannot recreate the problem locally. </p>
  
  <p>Ideally we want to somehow limit the CPU usage to maybe just a single core when browsing the website in the office so we can try and replicate the situation of our users.</p>
  
  <p>Is there any way of doing this?</p>
