You are aware that LAGG/LACP will give you only a single interface's = bandwidth for a single stream? That's by design, because reordering of TCP packets = is bad. You would need to test with multiple endpoints, because most commonly = distribution is per IP address hash. HTH, Patrick --=20 punkt.de GmbH Patrick M.
