BIG-IP dataplane's VMXNET3 driver implementation is missing the Receive Side Scaling (RSS) support for the User Datagram Protocol (UDP) available as part of the VMXNET3 version 4.
The traffic distribution does not happen evenly across all TMMs but rather all of the UDP traffic is sent to a single TMM.
BIG-IP VE instance is running on a VMWare host and handling UDP traffic.
