Most websites and web applications run smoothly and correctly as long as only one user (e.g. the original developer) or just a few users are visiting at a given time. But what happens if thousands of users access the website or web application at the same time?
Using Webserver Stress Tool you can simulate various load patterns for your webserver which will help you to find problems in your webserver set up. With steadily increasing loads (so called “ramp tests”) you are able to find out how much load you server can handle before serious problems arise.

Webserver Stress Tool is a powerful HTTP-client/server test application designed to pinpoint critical performance issues in your web site or web server that may prevent optimal experience for your site's visitors.
