Hi, Thank you for the response, The use of cbench is well defined in many documentations but I couldn't find explanation about its given output results, For example in these lines:
*20:37:19.352 1 switches: flows/sec: 101527 total = 10.137119 per ms * *20:37:29.458 1 switches: flows/sec: 95083 total = 9.502979 per ms * *20:37:39.558 1 switches: flows/sec: 111017 total = 11.101199 per ms* *...RESULT: 1 switches 9 tests min/max/avg/stdev = 547.22/11101.20/8529.18/3085.47 responses/s* it's giving flow/sec not fmod/sec, and then i find in previous work that they are plotting "flow/sec" not "responses/sec min/max/avg/..", So i got lost in understanding how they get those metrics ?? If I am not wrong, and as i understood from Wcbench's plotter code <https://github.com/dfarrell07/wcbench/blob/master/stats.py>, We only plot the last line metrics "RESULT:", but they'r min/max.. 2016-05-26 16:26 GMT+01:00 André Mantas <andremant...@gmail.com>: > I can try to explain what I understand: > > From the README page of cbench we get > > ./cbench -p 54321 > cbench: controller benchmarking tool > connecting to controller at localhost:54321 > faking 16 switches :: 16 tests each; 1000 ms per test > starting test with 0 ms delay after features_reply > debugging info is off > > > In this case cbench is running with default params (only port is set), > which means it is in latency mode.
