    what is the formula to calculate the pacing value?

    Thanks for such helpful content.

    Hi ,
    Hi i am seeing negative pacing value in pacing what would be reason for that.

      Hi Laxmikant,

      It means that your input (NFR) does not satisfy Little’s law. You need to provide realistic values. For example, if you want to calculate the pacing by providing 1 user with 100 seconds end-to-end response time for 100 iterations per hour then pacing will be negative, because such a scenario is practically impossible.

    just wanted to understand what if based upon input parameter i get negative pacing ?

    for exmaple :
    If i have given below inputs in the tool i get pacing as -8.5 , What i can interpret from this negative pacing ??
    Number of users 100
    End to End Response Time in (Seconds) 0.5
    Iteration per hout 180000
    Total Think Time in Second (0 for no think time) 10
    Calculated Pacing -8.5

      Hi Sumit,

      It means that the given values do not satisfy Little’s law and figures are unrealistic. In your case, 10 seconds think time is too much which you can control.

    please suggest how to do that:

    Please calculate pacing for the below requirement:
    #concurrent users: 5000
    5 scripts – concurrent users split is 10%, 25%, 20%, 25% and 20%
    Volume per hour: 15000, 25000, 2000, 40000, 30000
    #transactions per iteration: 5
    Timetaken for 1 iteration : 60, 80, 70, 30, 50 seconds.

      Hi Prateek,

      As you mentioned transactions per iteration is 5, so does it mean each script has 1 transaction?
