摘要
Optimizing network driver performance and power consumption in multi-core processor-based systems is disclosed. In this regard, a multi-core processor-based system provides multiple processor cores comprising one or more power-optimized processor cores and one or more performance-optimized processor cores, and a network device configured to assign network streams to a plurality of interrupts. A network driver calculates a current throughput level of the network device, and determines whether a throughput mode of the network driver should be modified to a high-throughput mode. If so, the network driver assigns each interrupt to one of the performance-optimized processor cores, and disables system reassignment of interrupts among the processor cores. Some aspects may also determine whether the throughput mode should be modified to a low-throughput mode, in which case the network driver assigns each interrupt to a same power-optimized processor core and enables system reassignment of interrupts among the processor cores.
