Hi all,
We are currently testing the OPNFV SFC testcase and we have come across some worrying performance issues. Specifically we are running script [0] to create 2 chains (consisting of 1 VNF each) and 2 classifiers. After the script execution has finished we time how long it takes until we see the first NXM_NX_NSP flow in table=11. I list these times below: 1 Compute node | 7s 2 Compute nodes | 16s 3 Compute nodes | 26s This measurements are confirmed when we do the same for script [1] 1 Compute node | 8s 2 Compute nodes | 17s 3 Compute nodes | 32s The delays are relatively big, but what we find especially worrisome is that the delays seem to grow with the number of Compute nodes almost linearly. This off course is unacceptable, as it cripples the ability to scale in large deployments. The question is, can these operations be run in parallel, so that we have almost constant delays relating to the number of compute nodes?
