Hi, So I changed the polling frequency interval in the function you mentioned (I re-did all the steps following updating ovs through mininet). However, the packet count changes after roughly 500 ms. Is there anywhere I can change that?
I tried changing the polling frequency to 1ms, 0.1ms and 0.01 ms (in the function you mentioned) and the achieved frequency is roughly around 1ms but when I check the packet from the fetched flow stats, they change after 500 ms. I have a long lived iperf flow which is running. Is there anything in the switch code which is limiting it?
