Appliances 5900 R80.10 and bonding interfaces limited throughput

Hi guys,

I have a clusterxl with two appliances 5900 and Gaia OS R80.10.

Network is configured with 2 bond interfaces 802.3ad layer 3+4, each bond has 4 ethernet aggregated, each bond has more vlan interfaces configured, about 10 in internal bond and 3 on external bond. All ethernet interfaces are connected to cisco switch with LACP configured, 2 groups.

No QoS is configured, no IPS is configured only security policies with about 50 rules.

My test is simple I trying to transfer data beetween vlan on internal bond and my speed is about 3Gbps and somethings more, the same test on external bond I got 3Gbps.

When I trying to transfer data beetween vlan on internal bond and vlan on external bond, I reach the limit of ethernet interface 1Gbps. Why?

In my test I have used different source address and destination address so also TCP ports all different

While my test is executing I can see in cpview the throughput on each interfaces, I can see the traffic is balanced beetween they but the sum don't go over 1Gpbs when I use vlans on both bond interfaces, but when the vlan is on same bond interface I see more interfaces reach the limit of 1Gbps so the sum on bond interface is over the 1Gbps and I got 3Gbps and more of throughput.
