It same more nics aggregation and get more bad performance .
Does this is a konwn Bug ?
Can networking guys give us some advise? It's really very important for us.
Your traffic is spread only on three ports out of four. Both on the
outbound side from the host and from the switch side to the host. It
seems that you may not have enough traffic streams going over your
aggregation to obtain distribution over all four ports.
Nicolas.
