More Information
Summary:An information handling system (IHS) includes a plurality of processors that include a cache memory, and a receive side scaling (RSS) indirection table with a plurality of pointers each pointing to a processor. A network data packet received by the IHS determines a pointer to a first processor. In response, information associated with the network data packet is transferred to the cache memory of the first processor, The IHS also includes a process scheduler that moves a process associated with the network data packet from a second processor to the first processor, and RSS module that directs the process scheduler to move the process and associates the first pointer with the processor in response to directing the process scheduler. In one embodiment, the processes are virtual machines so that network packets associated with a virtual machine are processed by sending an interrupt to a processor supporting executing the virtual machine.
