Response Time


Response Time report represents the values of server response time. Average and maximum response times are the most important characteristics of load testing. They tell you how long a user waits for server response to his request. You should ensure that users of your site/application get the response in acceptable time.

There are 3 important limits for response time values:
0.1 second. It is an ideal response time. Users feel that the system is reacting instantaneously, and don't sense any interruption.
1.0 second. It is the highest acceptable response time. Users still don't feel an interruption, though they will notice the delay. Response times above 1 second interrupt user experience.
10 seconds. It is the limit after which response time becomes unacceptable. Moreover, recent studies show that if response time exceeds 8 seconds, user experience is interrupted very much and most users will leave the site or system.

Normally, response times should be as fast as possible. The interval of most comfortable response times is 0.1 - 1 second. Although people can adapt to slower response times, they are generally dissatisfied with the times longer than 2 seconds.

Click on the Response Time subfolder of Summary Report folder in the Navigation Pane to view the Response Time report.



You can see values of response time for each request, as well as minimum (Min), average (Avg), Avg80-99 and maximum (Max) values of response time.

Next to the name of each request you can see how many times it was processed at the specified periods of time.

If some column in the table is empty, it means that request wasn't executed during a period specified in column header. Decrease the Number of columns in tables value in Log and Report Settings. Then time intervals in column headers will be increased. Run the test again to verify that you get correct results.

Task time




This table shows the time of processing of various tasks that you added to user profiles. A task is a sequence of requests inside the Task operator. The program calculates the total time of processing of such sequences of requests.

In the table you can see the minimum (Min), average (Avg), Avg80-99 and maximum (Max) values of task time.

Next to the name of each task you can see how many times it was processed. In other words, you can see the number of completed tasks. A task is considered completed if all its elements were completed.
