You should use better hashing algorithms for LACP.

Take a look at this explanation: https://www.ibm.com/developerworks/community/blogs/storageneers/entry/Enhancing_IP_Network_Performance_with_LACP?lang=en

In general only L2 hashing is made, you can achieve better throughput with L3 and multiple IPs, or with L4 (ports).

Your switch should support those features too, if you’re using one.

The problem isn't the LACP connection between the host & the switch, but setting up LACP between the VM & the host. For reasons of stability, my 4.1 cluster's switch type is currently "Linux Bridge", not "OVS". Ergo my question, is LACP on the VM possible with that, or will I have to use ALB?

Hi All,
My hosts have all of their interfaces bonded via LACP to maximise throughput, however the VMs are still limited to Gbit virtual interfaces. Is there a way to configure my VMs to take full advantage of the bonded physical interfaces?

One way might be adding several VIFs to each VM & using ALB bonding, however I'd rather use LACP if possible...
