Understand packet-processing performance when employing multicore processors - Your cache configuration can have a bigger impact on overall system performance than you expect

摘要

Many CPU manufacturers now deliver two cores per processor socket, with four cores on the way, and even more to follow. But harnessing multicore processor performance depends on the software developers' ability to make efficient use of these additional cores. Multicore processors offer developers more avenues to increase their systems' compute performance. With more cache memory available, it's possible to optimize the locality of data references, which in turn drives higher cache hit rates.
