How to Define Pacing in Load Testing

 Pacing Calculation :-

 D = Duration of the test(test window/time frame)
 B = Baseline time(total time taken by 1 Vu to complete 1 whole iteration)

 T = Total amount of Think time in the script

 I = Expected/Target iteration

 R = Residual time of the test window.

 R = ( D - (T + B)*I)

 P = Pacing interval

 Dividing the residual time by target iteration gives pacing interval

 P = R/I 

D is pacing time.
(T + B)*I represents the duration of a scenario
and P is the waiting time before the next scenario
