Abstract — In order to capture packet traces at high speed using a low-cost platform, we have to optimize the networking stack of a general purpose operating system. Different techniques are compared with the final objective of avoiding packet loss. Among those techniques we will study the performance of NAPI [6] and PF-RING [9]. Depending on the final application, we should tune certain parameters accordingly. We also present the advantages of a multiprocessor platform and the problematic of storing full packets directly to hard disk.
