So, my question is - is it worth to stick to pf/ALTQ on > 10G interfaces ? Will pf carry such traffic ? > Be aware that ALTQ will not let you configure queues with that sort of bandwidth. All of the datatypes used are 32-bit integers and top out at 2 or 4 Gbps. Unfortunately dummynet has exactly the same problem, so switching to ipfw won’t help. Regards, Kristof
