An approach for a dynamic provisioning of multiple RSS engines is provided. In an embodiment, a method comprises monitoring a CPU usage of hardware queues implemented in a plurality of RSS pools, and determining whether a CPU usage of any hardware queue, implemented in a particular RSS pool of the plurality of RSS pools, has increased above a threshold value. In response to determining that a CPU usage of a particular hardware queue, implemented in the particular RSS pool, has increased above the threshold value, it is determined whether the particular RSS pool includes an unused hardware queue (a queue with light CPU usage). If such an unused hardware queue is presented, then an indirection table that is associated with the particular RSS pool is modified to remap one or more data flows from the particular hardware queue to the unused hardware queue.

An approach for improving throughput for encapsulated network traffic is provided. In an embodiment, a method comprises obtaining a plurality of network addresses of a plurality of intermediaries that facilitate communications between a plurality of virtual machines. A set of source-destination intermediary pairs is determined based on the plurality of network addresses, and for each source-destination intermediary pair, from the set of source-destination intermediary pairs, a precomputed encapsulated header is generated and included in a set of precomputed encapsulated headers. If a data packet from a particular source intermediary and destined to a particular destination intermediary is received, and a particular precomputed encapsulated header for the particular source intermediary and the particular destination intermediary is included in the set of precomputed encapsulated headers, then the particular precomputed encapsulated header is retrieved from the set of precomputed encapsulated headers and used to form a particular encapsulated packet.

Some embodiments provide a method for selecting a transmit queue of a network interface card (NIC) of a host computer for an outbound data message. The NIC includes multiple transmit queues and multiple receive queues. Each of the transmit queues is individually associated with a different receive queue, and the MC performs a load balancing operation to distribute inbound data messages among multiple receive queues. The method extracts a set of header values from a header of the outbound data message. The method uses the extracted set of header values to identify a receive queue which the NIC would select for a corresponding inbound data message upon which the NIC performed the load balancing operation. The method selects a transmit queue associated with the identified receive queue to process the outbound data message.
