Think time is the time spent by a user perusing a Web page, including viewing the page and determining the next action. Think time does not include the time that is required for a page to load.
When you record a Web performance test, think times are recorded for each Web page. Later, when you run the Web performance test, the think time can be either used or ignored. In the Web Performance Test Results Viewer, use the Think Time button to switch from using think times to not using them.
Think times are very important during load tests because they set the pace of the test. It is important to review the recorded think times of your Web performance tests to make sure they accurately reflect realistic wait times. It is easy to be distracted during a recording session and have unexpectedly long think times that have an adverse effect on a load test. To avoid this problem, you can pause the recorder.
