Dears I did a latency test for an OpenFlow controller by cbench tool, the results is bellow: -K56CB:~$ taskset -c 0-3 cbench -c localhost -p 6633 -m 10000 -l 14 -w 2 -M 100000 -i 50 -I 5 -s 1 cbench: controller benchmarking tool running in mode 'latency' connecting to controller at localhost:6633 faking 1 switches offset 1 :: 14 tests each; 10000 ms per test with 100000 unique source MACs per switch learning destination mac addresses before the test starting test with 0 ms delay after features_reply ignoring first 2 "warmup" and last 0 "cooldown" loops connection delay of 50ms per 5 switch(es) debugging info is off 13:56:05.830 1 switches: flows/sec: 635968 total = 63.596794 per ms 13:56:15.931 1 switches: flows/sec: 765060 total = 76.505992 per ms 13:56:26.031 1 switches: flows/sec: 763596 total = 76.359592 per ms 13:56:36.131 1 switches: flows/sec: 765249 total = 76.524892 per ms 13:56:46.232 1 switches: flows/sec: 757221 total = 75.722062 per ms 13:56:56.332 1 switches: flows/sec: 771945 total = 77.194492 per ms 13:57:06.432 1 switches: flows/sec: 755700 total = 75.569992 per ms 13:57:16.532 1 switches: flows/sec: 755304 total = 75.530392 per ms 13:57:26.632 1 switches: flows/sec: 754737 total = 75.473692 per ms 13:57:36.733 1 switches: flows/sec: 755922 total = 75.592192 per ms 13:57:46.833 1 switches: flows/sec: 756075 total = 75.607492 per ms 13:57:56.933 1 switches: flows/sec: 757404 total = 75.740392 per ms 13:58:07.033 1 switches: flows/sec: 761826 total = 76.182592 per ms 13:58:17.134 1 switches: flows/sec: 772500 total = 77.249992 per ms RESULT: 1 switches 12 tests min/max/avg/stdev = 75473.69/77249.99/76062.31/614.30 responses/s Does it right that the calculation for the latency is done by dividing 100000 to the resulted number 76062.31 to get the average delay for all the tests in Microseconds.
