Do the recent tcpdump releases use the shared memory functionality of the newer libpcap libraries? Basically, if I download the latest tcpdump and the latest libpcap and compile them on FreeBSD and on Linux, and then run the binary, will I get the speed advantages of mmap()? Or are there other things that I have to do, tcpdump/libpcap or maybe OS related? Thanks Jon On Sun, Nov 27, 2011 at 11:15 PM, Guy Harris <guy () alum mit edu> wrote:

I know that there are some other that have modified libpcap to use mmap() such as Phil's: public.lanl.gov/cpw I was just curious to whether you guys have anythingYes, we have some things called "libpcap 1.0" and "libpcap 1.1". :-) Support for both Linux and FreeBSD memory-mapped capture has been in libpcap since 1.0. - This is the tcpdump-workers list.
