Response Time
Response Time report represents 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 times longer than 2 seconds.
Click on Response Time subfolder of Summary Report folder in Navigation Pane to view
the Response Time report.
You will see values of response time for each request. The whole test
duration interval is divided into the number of intervals equal to HTML
report dimension value. The program calculates values of response
time through these intervals and shows them in corresponding columns.
You can see the minimum (Min), average (Avg), average calculated
for 90% of all participated users (Avg90) and maximum (Max)
values of response time. If you watch this table during test run, you
will see how it is being filled in: one column after another until the
last column is filled in.
If response time in some column is equal to zero, it means that current request wasn't
executed during period specified in column header. You should do one of the following to
verify that you get correct results:
Decrease HTML report dimension value in Log
and Report Settings
It is the number of columns displayed in current report and some other tables of
Summary Report and HTML Report. The number of columns is the number of time
intervals of the whole test duration interval.
If the tested server cannot
execute an adequate number of requests during time interval specified in column header,
you should reduce the number of columns.
Increase the Refreshing time in Log and Report Settings
It is time period (in seconds) after which the program refreshes statistics of gathered data
in generated graphs and reports.
If Refreshing time is too small, the tested server won't be able to execute an
adequate number of requests
during this time. You should increase Refreshing time value to get correct results.
Saving the Response Time report You can save the Response Time report as HTML
file in required location. For this, right-click on the displayed report
and select Save Current Report to HTML... option on the context
menu. In the displayed dialog, enter file name, select a location and
click Save. You will be able to view this report later, any time
you wish just from web browser. It is also a convenient way to transfer
test results to any interested person.
