You can improve VLAN-VXLAN bridging throughput using Software Receive Side Scaling.
Prerequisites
- Verify that you have NSX 6.4.2 or later installed.
- Determine which hosts should have SoftRSS enabled.
- Enable SoftRSS on the ESXi hosts on which the active/standby bridge exists (where the DLR Control VMs are hosted). If the Control VMs might be migrated using vMotion, enable SoftRSS on all the hosts in the cluster.
- If Default Queue Receive Side Scaling (DRSS) is supported on the host physical NIC, enable that and do not enable SoftRSS. Use esxcli system module parameters list -m [nic_module] to verify if DRSS is supported.
