Short answer: no… But don't leave us now ! Read the end of my mail please :-) Theorically the FreeBSD version that can give you more performance should be the -current or 9-stable because they included latest NIC drivers. Tuning network stack on FreeBSD is not very easy and I would like to compile all informations and tuning tips for document this part. My idea is to to provide a simple shell script that collect server inventory and under-load statistics for proposing tuning advice… And your running system can help us. Can you answer to these questions: Regarding your sysctl.conf: Why "kern.ipc.nmbclusters = 512000", and not a smaller or bigger value ? How did you choose this exact value ? Same question for "kern.ipc.nmbjumbop = 256000" and "hw.intr_storm_threshold = 9000" => There are lot's of "tuning" guide that give these kind of raw numbers, but neither explain how to calculate these number for your needs. And a a router can't be tuned like a firewall or a end-host. Then can you post (during high load) the output of vmstat -i => interrupt rate top -SCHP => Core/NIC queue usage netstat -Q => netisr stats netstat -m => mbuf usage netstat -B => for checking if BPF is used or not (performance impact) And your hardware detail and ixgbe stats: cat /var/run/dmesg.boot => Can be interressing message during loading NIC drivers pciconf -lvc => Exact chip number and PCI bus information ifconfig -m => NIC capabilities and status sysctl hw.ixgbe sysctl dev.ixgbe => Tuning parameters regarding ixgbe drivers sysctl net.route sysctl net.isr => netisr configuration sysctl net.inet.ip => gloal IPv4 configuration sysctl net.inet.raw => maximum datagram length sysctl sysctl net.inet.flowtable => For checking if you use or not flowtable kldstat -v => For checking all modules loaded (and if you are using pf on ipfw) Thanks, Olivier ------------------------------------------------------------------------------ Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!
