Was the user-mode Snort using Phil Wood's libpcap <http://public.lanl.gov/cpw/> or an older version without MMAP mode support?we compared against regular (0.8.3) pcap, so Phil Wood's version should be considerably faster.Cool, thanks for the clarification.However, speed-ups can still be obtained by running in the kernel due to fewer context switches and no need for copying a packet into the memory mapped area.Agreed. Do you have any plans to benchmark against Phil Wood's version in the future?
Well, I'm no longer being paid to work on this, so - honestly - changes that I'll be testing it are slim. However, other are improving FFPF. In case we are going to test some more I will suggest running Phil's version as well. By the way, have you ever looked into Luca Deri's PF_RING solution? He obtained very good results with a hybrid between Phil's and our implementation. Perhaps he has tested against the regular mmapped pcap. I don't know. Find it at luca.ntop.org or through googling. cheers Willem ------------------------------------------------------- This SF.Net email is sponsored by: thawte's Crypto Challenge Vl Crack the code and win a Sony DCRHC40 MiniDV Digital Handycam Camcorder.
