Hello all, I have a question about the throughput calculation in Jmeter.
I set up a simple test plan and I configured jmeter to print information about the throughput using the information found in: http://jmeter.apache.org/usermanual/component_reference.html#Generate_Summary_Results The results I got are the following: summary + 1 in 0.2s = 4.6/s Avg: 218 Min: 218 Max: 218 Err: 0 (0.00%) Active: 3 Started: 3 Finished: 0 summary + 92 in 5.3s = 17.2/s Avg: 784 Min: 199 Max: 1409 Err: 0 (0.00%) Active: 34 Started: 34 Finished: 0 summary = 93 in 5.3s = 17.4/s Avg: 778 Min: 199 Max: 1409 Err: 0 (0.00%) summary + 113 in 7.3s = 15.4/s Avg: 2068 Min: 1413 Max: 2638 Err: 0 (0.00%) Active: 60 Started: 60 Finished: 0 summary = 206 in 11.3s = 18.2/s Avg: 1485 Min: 199 Max: 2638 Err: 0 (0.00%) summary + 130 in 9s = 14.7/s Avg: 2829 Min: 2461 Max: 3128 Err: 0 (0.00%) Active: 60 Started: 60 Finished: 0 summary = 336 in 17.4s = 19.3/s Avg: 2005 Min: 199 Max: 3128 Err: 0 (0.00%) summary + 123 in 9s = 13.8/s Avg: 2878 Min: 2574 Max: 3082 Err: 0 (0.00%) Active: 60 Started: 60 Finished: 0 summary = 459 in 23.3s = 19.7/s Avg: 2239 Min: 199 Max: 3128 Err: 0 (0.00%) summary + 127 in 9s = 14.3/s Avg: 2873 Min: 2554 Max: 3200 Err: 0 (0.00%) Active: 60 Started: 60 Finished: 0 summary = 586 in 29.3s = 20.0/s Avg: 2376 Min: 199 Max: 3200 Err: 0 (0.00%) summary + 125 in 9s = 14.0/s Avg: 2876 Min: 2614 Max: 3090 Err: 0 (0.00%) Active: 60 Started: 60 Finished: 0 summary = 711 in 35.3s = 20.1/s Avg: 2464 Min: 199 Max: 3200 Err: 0 (0.00%) I am a little bit lost here. Why is the sum of all the intermediate intervals higher than final time? If I did the math right the sum should be 48.8 while the final interval is 35.3. Why is the final throughput (that should be the cumulative) higher than all the intermediate? Could you please explain me how to read those results? Thank you very much for you support and congratulation for your job Best regards Sebastiano --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
