Webserver Stress Tool offers three main test types

· CLICKS: the test is finished when each user has initiated the given number of clicks. CLICKS tests are the right choice to test specific URL sequences.
· TIME: tests that run for a specified number of minutes. A timed test is often used for “burn in tests”, e.g. to keep a server under full load for 10 hours.
· RAMP: Ramp tests also run for a specified time, but with increasing load from 1 user to the specified number of users which is reached at 80% of test time. During the last 20% the full number of users is active. A Ramp Test is a great way to find out the limitations of your webserver or web application.
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.
