title: How to stress test simulating heavy load using Selenium
body: <p>I have a system to test, which is a video ads distribution technology. I need to load every video like 1-2 mins to serve the ads. The videos are played in a Flash client and streamed as FLV streams like in YouTube.</p>
  
  <p>The reason why I need to test it only via browsers -- and every other method won't work -- is to stress test both the video streaming servers and the ads servers simultaneously and displaying ads in real-time.</p>
  
  <p>I have used Selenium, WatiN, Automation Anywhere and many other automation tools. However, when I am trying to start like 10000 browsers on my machine (32GB RAM, 16-core CPU), none of them are able to do the job.</p>
  
  <p>With Selenium, I am able to start the maximum FireFox instances so far, but that's still too low: half of the instances don't run the test.</p>
  
  <p>Any suggestions to do with Selenium?</p>
