    V users v/s elapsed time

    Hi,

    How to analyse vusers v/s elapsed time.
    im using opensta and not sure about how to analyse vusers with elapsed time.
    Results i obtained is like:
    for 1 user, elapsed time= 6secs
    for 100 users, elapsed time= 57 secs.so 57 divided by 100 users gives me .57secs. which means that the elapsed time is decreased with increase in vusers.
    is this analysis correcty. If not how do i do it. plz help!!


    Regards,
    Archana

    Re: V users v/s elapsed time

    hi Archanah,

    Are you talking about active users vs Elapsed time graph?
    some times it is possible.

    What about the rest of your performance counters/Timer values? is it acceptable ?

    thanks and regards

    Re: V users v/s elapsed time

    Read this, it gives instructions on how to download a spreadsheet that will do the calculations you need. Also, this has a good overview of the capacity testing process. The end of this pdf file shows one method of applying load in a step wise fashion which allows the system to settle into a steady state so that graphs for average response time vs users and CPU utilization vs users can be can be created. Absent any absolute criteria for response times, the capacity limit of a system can be found by finding the point at which a small increase in VUs results in a large increase in response times.
