Nowadays commodity hardware is offering an ever increasing degree of parallelism: CPUs are equipped with more and more cores and a new generation of NICs can dispatch packets across multiple queues. Software based network moni- toring can leverage the opportunity offered by this new trend in order to target a level of performance which was unattainable with single core technologies. In this paper, which is the result of a thorough measurement campaign, we explore the potential of parallelism when coupled with existing packet capturing technologies and show how, by accurately tuning configurations, a huge performance gain can be obtained. We also show how minimal configuration changes can dramatically affect the overall throughput.

Abstract

Nowadays commodity hardware is offering an ever increasing degree of parallelism: CPUs are equipped with more and more cores and a new generation of NICs can dispatch packets across multiple queues. Software based network moni- toring can leverage the opportunity offered by this new trend in order to target a level of performance which was unattainable with single core technologies. In this paper, which is the result of a thorough measurement campaign, we explore the potential of parallelism when coupled with existing packet capturing technologies and show how, by accurately tuning configurations, a huge performance gain can be obtained. We also show how minimal configuration changes can dramatically affect the overall throughput.
