Subject Generate Summary Results - Incorrect Calculations?
Date Wed, 07 Jan 2009 14:07:39 GMT
Help please . .

I'm I misinterpreting the summary results? Take the following for example . .

Generate Summary Results +   127 in  14.4s =    8.8/s Avg:   122 Min:     7 Max: 783 Err:
    0 (0.00%)
Generate Summary Results +  7681 in 179.9s =   42.7/s Avg:  1269 Min:     1 Max: 17388 Err:
    0 (0.00%)
Generate Summary Results =  7808 in 194.3s =   40.2/s Avg:  1251 Min:     1 Max: 17388 Err:
    0 (0.00%)
Generate Summary Results + 10258 in 192.9s =   53.2/s Avg:  3589 Min:     1 Max: 43845 Err:
    3 (0.03%)
Generate Summary Results = 18066 in 374.3s =   48.3/s Avg:  2578 Min:     1 Max: 43845 Err:
    3 (0.02%)
Generate Summary Results + 11856 in 188.9s =   62.8/s Avg:  2683 Min:     0 Max: 45321 Err:
    6 (0.05%)
Generate Summary Results = 29922 in 554.4s =   54.0/s Avg:  2620 Min:     0 Max: 45321 Err:
    9 (0.03%)

Total number of requests are an addition of requests made in each interval -  127+7681+10258+11856
= 29922

Total time would then, you would assume, be an addition of each of the interval times - 14.4+179.9+192.9+188.9
= 576.1s
However, total time seems to be calculated as -  14.4+180+180+180 = 554.4s

Where 180s is the default interval time.

When calculating total request per second, the calculation is:

29922 / 554.4 = 53.97 requests per second

As opposed to:

29922 / 576.1 = 51.94 requests per second

Is there not a discrepancy in the total elapsed time and therefore the requests per second
or am I completely misunderstanding the results given?

Any help clarifying this would be greatly appreciated.


Thanks in advance,


Simon.
