    Test Complete 6 Load Test Issues

    Why is it everytime when I conduct a load test and view its results, the time taken for it to perform a query does not seems to matches the system time ?

    <u>I.E. :- User Login Menu</u>
    According to the system time, it will only take a mere 1 to 2 seconds for it to process. But when its executed via TC6, the results shown is within the range of 3 to 5 seconds (Note: 5 virtual users are created)

    Another predicament encountered is whenever the first load test runs, the time taken will be somewhere within the range of 5 to 10 seconds (taking the User Login Menu as the scenario example). But when it undergoes a second run, the time taken will be less. Can anyone justify your verdicts ?

    On an additional annotation, when we export the results out to IE, how can we derive a finalized conclusion from the graph ?

    Hello Steven,

    Where do you see these numbers? I recommend that you go through the "HTTP Load Testing - Timing Task Execution" help topic to learn more about the meaning of the numbers shown in the Load Testing log.
    Try looking at the pure request execution time - it is shown in the "Request Execution Summary" parameter for connections. It should be close to your observations.

    I am not 100% sure about your situation, but most likely the difference that you see is caused by the fact that internal TestComplete mechanisms are initialized on the first run.

    Re: Test Complete 6 Load Test Issues

    AS for the result... where are oyu looking at those numbers? If you're looking at the test log, that's not an accurate timer for the actual server response time. There are detailed load testing logs you should be looking at.

    As for the time being less on a second run, in the case of our web app, if the app has not been hit initially, there's some "spin up" time that the server needs to do in order to initialize the app under test. Each subsequent request after that does not need that spin-up time. Does your app have similar behaviour?
