Abstract: A host computer has a plurality of containers including a first container executing therein, where the host also includes a physical network interface controller (NIC). A packet handling interrupt is detected upon receipt of a first data packet associated with the first container. If the first virtual machine is latency sensitive, then the packet handling interrupt is processed. If the first virtual machine is not latency sensitive, then the first data packet is queued and and processing of the packet handling interrupt is delayed.

Abstract: A host computer has one or more physical central processing units (CPUs) that support the execution of a plurality of containers, where the containers each include one or more processes. Each process of a container is assigned to execute exclusively on a corresponding physical CPU when the corresponding container is determined to be latency sensitive. The assignment of a process to execute exclusively on a corresponding physical CPU includes the migration of tasks from the corresponding physical CPU to one or more other physical CPUs of the host system, and the directing of task and interrupt processing to the one or more other physical CPUs. Tasks of of the process corresponding to the container are then executed on the corresponding physical CPU.

Abstract: Techniques disclosed herein provide an approach for using receive side scaling (RSS) offloads from a physical network interface controller (PNIC) to improve the performance of a virtual network interface controller (VNIC). In one embodiment, the PNIC is configured to write hash values it computes for RSS purposes to packets themselves. The VNIC then reads the hash values from the packets and places the packets into VNIC RSS queues, which are processed by respective CPUs, based on the hash values. CPU overhead is thereby reduced, as RSS processing by the VNIC no longer requires computing hash values. In another embodiment in which the number of PNIC RSS queues and VNIC RSS queues are identical, the VNIC may map packets from PNIC RSS queues to VNIC RSS queues using the PNIC RSS queue ID numbers, which also does not require the computing RSS hash values.
