Does the memcpy libpcap verions perform well? Indeed, on this point I invite others to give their opinion. My generic feeling is that a commodity P4 box should be fine. If SMP hardware (eg. 2 CPUs) is affordable, it would be even better. Then, because libpcap-mmap comes at no extra cost (ie. doesn't require any kernel hook or recompilation), I would invite to use that instead of the plain (memcpy) version. Such assumption would break only for who in the need of filtering over the MPLS chain (because a recent libpcap is needed but libpcap-mmap seems it hasn't been updated since August). Cheers, Paolo
