Actually it is in between. What happens is that libpcap requests a PF_PACKET
Hi,
Regarding the OS we have done testing on this some five years ago. Back then we
found that FreeBSD performed better than Linux. Yet there have been
improvements proposed for both Linux (memory mapping, and Luca Deri's work) and
FreeBSD (zero-copy BPF and Alexandre Fiveg's work). To get
