        Hi,
        Did you test from www.speedtest.net also to make sure nothing is wrong with nperf?

            That's still the difference between bits and Bytes. What exactly are you expecting to see on the traffic graph there?

              Just to make it clearer, speedtest websites generally use Mb/s which is "Mega-Bits per second".

              PfSense has the option to display in either Bits/sec or Bytes/sec. You need to select "bits" for the Unit Size.

                What I found strange is not bits, bytes, ...
                It concerns the values.
                I mean :
                Measured by speedtest : 150 while pFsense measure more than 200
                Same with nperf measure : 189 while pFsense measure much more than 200

                But you are right.
                Setting pFsense using "Bits" give the same as Speedtest.

                Thanks you very much for answering and explanations.

                  What sort of WAN connection do you have? Something with overhead like PPPoE or over some VPN?

                    Just a fiber link with a french box named "Freebox".

                    Fiber ------>  Freebox -----------> pfsense  ------------->  LAN
                         82.x.x.x          192.168.0.x            192.168.20.x

                        pfsense ?
                        DNS resolver, DHCP, VPN (OpenVPN) when I'm out of home, PABX (via WAN to SIP account and via VPN when I'm out of home) + IP phone on LAN, VLAN for cameras, pfBlockerNG
                        And also some QoS for VoIP.

                          No I mean the WAN type? If the WAN is something encapsulated then that would mean additional traffic on the NIC.

                              @Autourdupc No he means like some sort of tunnel, or something like PPPoE

                              Also keep in mind speed test is only showing you from and to your specific client and their servers.. while the interfaces on pfsense are going to show all traffic.. If your network is quiet while testing there shouldn't be much difference.. But its never going to be exactly the same - for starters on the wan there always going to be some noise level.. And same with lan you could have other traffic that doesn't even go out the wan or it might.

                              Also they are presenting you with 1 number, which is not the case with pfsense showing you a graph.. that data flow rate is going to fluctuate - they present just 1 number, which is never the case.. It doesn't jump to 100, and stay exactly at 100 for 30 seconds.

                              Also the graph on pfsense is going to do smoothing of what it presents of some different degrees..

                              I really wouldn't worry about it as long as your in the same ball park number.. But yeah you have to look at the numbers either both bits or both bytes and or do the math conversion in your head.. Because there is a 8X difference between B and b..
