          How does that divide across the cores? I imagine you have one core at 100%

            one core is reaching 100% yeah…rest of them are low in load.

              Are you able to adjust this over the PowerD function perhaps?

                According to what I have found on the forum this is meant to be  "adaptive"
                Found that we can change the parameters by editing /etc/inc/system.Inc
                Or în gui via system - advanced - miscellaneous.

                  Yes this I was meaning, by an Alix APU we where seeing the throughout gaining
                  from ~450 MBit/s to 650 - 750 MBit/s only by activating or changing the PowerD options.

                          It explains the low throughput in one direction but there's no solution to it as yet. Havne't tried the suggested patch but we are at least aware of it now.

                                I found another thread pointed to this circumstance where this would be really nice explained.
                                mbufs tunable
                                Also have a dedicated view on the named pfSense versions please.

                                  Nikkon, you only have one queue per NIC in each direction? You have a 4 core CPU I expect to see at least 2 queues. Do you have a tunable set to limit that?

                                    Is there a recommanded value?

                                        I have seen copy speeds between 2 freebsd10 hosts via dd and mbuffer of 1115 MiB/s and actual file copy with zfs send and receive through mbuffer of 829 MiB (disk system limitation)
                                        Could not get iperf to fill the link..

                                        That is with supermicro X9 mainbords and Xeon 1220 CPU via X520-DA2 nics. No tuning at all.
                                        I tried a lot of tuning of parameters and it did not do much for me. But it might be different for Firewall usage.

                                          I my opinion that is something like we talk about ZeroShell, IPCop, IPFire and SmoothWall and someone
                                          is reporting the throughput between two Linux hosts. Can be that I am wrong with this, because pfsense
                                          is based on FreeBSD, but as I read here in the forum there changes where done that it is not really more
                                          matching the ordinary FreeBSD now. Correct me please if I am wrong with this.

                                            Well, these systems are standard freebsd 10 and 10GE works line rate on 1500 MTU without any tweaking. I tried a lot of buffer setting till i found out it did not matter much.
                                            It was just finding the proper way to fill the interface up.

                                            I wrote this since i saw lots of posts with all kind of proposed changes.
                                            If this is far off the subject any admin can remove it, no problems, just thought i could add something usefull.
