Published on

Now you have finished your site and someone asked you the question: How many users can we serve before we need more power and muscle on our server environment? Good question! And if you don't know how to find that out, how to measure it, and find the bottle necks, come to this session. You’ll find out how to get started and learn more about tools for Coldfusion application load testing and how to use them.
