Abstract
A computing device receives a first data packet at a network interface card. The network interface card asserts a hard interrupt request on a first processing device based on a interrupt affinity value. A latency reduction module consults a data structure to identify a second processing device and schedules a soft interrupt request for the first data packet on the second processing device. The latency reduction module determines if an affinity threshold is met, and if the affinity threshold is met, updates the interrupt affinity value to reflect the second processing device.
