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.
