What good is a web stress test if it generates hundreds of pages of charts and tables that no one can figure out? That's why our user capacity analysis clearly measures your site's capacity based on either simple performance goals or complicated Service Level Agreements (SLA). You can use our default performance goals, or get as detailed or as technical as you like. A high level user capacity overview helps you quickly and easily see how many users your site can handle.
The analysis is done by looking at performance from both the client's perspective in terms of web page load times, and from the server's perspective on back end performance. The load is slowly raised, and measurements taken at each load level. Performance is measured at each load level and compared to the performance goals. When enough web pages are performing worse than their specification then the website is no longer performing within specifications.
Because some sites are more complicated than others, you can either set simple goals for an entire website, like most pages most load in two seconds or faster, or set different goals for different sections of the website. For example, most users want the home page to load very quickly, but will want for much longer while a credit card is being processed.

"I need solid web testing that I can rely on. I can't spend forever setting up tests and tweaking them a thousand ways. We jam out web code fast and we need a tool that is quick to set up, quick to test and quick to resolve issues. I often don't have more than a day to build the tests and get them done. The tool is a sanity check so nothing bites us after launch. Thanks for making my life easier."
