hi, after reading a german master thesis [1] (dated 12/2004) about pcap performance (with comparison of linux and freebsd) I searched freebsd resources for pcap improvements. Unofortunately I did not find any improvements like PF_RING and/or efforts for reducing the number of copy operations from device to user space. Maybe I think too simple because I don't know how SMP fine locks are influencing this (maybe it is very complex to improve that when you want to avoid side effects.). Or maybe it is not important at all, because real applications use DAG boards? I would appreciate any discussion here. greetings, Jochen [1] www.net.in.tum.de/teaching/projects/docs/schneider_SEP_slides2.ps [2] www.endace.com -- Dipl. Inf.
