I've tested out with 400 EVCs, in total 3209 flows (a bit more than what AmLight currently has in prod), they all got updated as expected, including a restart, tested with sdntrace_cp afterwards too to ensure it was all set. It went as expected, no alien or missing flows on consistency check were triggered. I documented on the README.md file.
