    Yrs the game tells me, however only if i pull up a menu while in multiplayer... it's BO4. I suspect, however there to be quite a bit of variation and i would be interested in finding out exactly when i suffer form it more.
    The box tells me it's 25/30ms. but at times i catch it with over 400ms latency, Are bursts of it.

      What does the quality graph show you for latency to your gateway - does it fluctuate a lot?

      If you saturate your line that latency can for sure go up.. Is your xbox wireless.. LIke I said jitter on wireless can be high..

      Once the packet leaves pfsense - how long it takes to get to answer depends on a whole lot of shit... The only thing you can do to control latency locally is going is to make sure your local network is not the problem..

        here is the graph. I do not use wireless. I prefer wired.

          .02 to .04 ms??

          WTF dude are you running? Never seen even lan ping times that low..

          0.00003 seconds... Come on...

          Are you pinging the boxes own IP? That is not really a test of network latency..
          That is pfsense pinging itself.. Sure ok if that was high then something major wrong.. But that doesn't tell you how long it takes to get from pfsense to where your going and back ;)

            yes. what should i ping? The problem is i do nto know which is the server i am connecting too...
            That is why i wanted a monitoring tool so that i can check what the box connects to.
            LOL, my bad, i am a bit unprepared. . .

              Ping the IP of the game server, ping pfsense IP from a device ON your network.. Not pfsense pinging itself ;)

              Ping your isp gateway from device on your network... That would show you if pfsense slowing you down..

                  Yeah that looks pretty typical.. and not bad..

                  That is some IP on the internet - is that your game server your playing on... That is pretty good to be honest..

                  That is a google IP ;)

                      look in the game.. What is the FQDN of it - how do you connect to it? Look in pfsense for the connection to the port you use int he state table, etc.

                        the xbox does not tell me where i am connected to unfortunately, i have to use PfSense for it, and i am not sure i know how....
                        Everything in Xbox is handled behind the hood. I just launch the game and the multplayer part is activated by default. I select matchmaking and the box handles the deal... but i fear that at times i may be connected quite far away, and that impacts a bit how the game plays.

                          So do you know what port(s) the game uses? Pretty sure you could look it up for firewall for the game... Then look in your state table for destination IPs going to those port(s)

                            Sure,
                            TCP: 53, 80, 3074
                            UDP: 53, 88, 500, 3074, 3075, 3544, 4500

                              Yeah some of those are BS.. 53 and 88..

                              But ok look for some sates in your state table for say 3074 while playing the game..

                                Here are some,

                                185.34.107.128:3074 outgoing
                                184.155.109.165:3074 incoming
                                99.45.180.232:3074 incoming

                                Plus these
                                172.16.1.10:3074 -> 13.89.46.200:3544
                                13.89.46.201:3544 -> 172.16.1.10:3074

                                Quite a few states have around 10 packets or just over it. some states have kbps.

                                    Like most console games it's likely using p2p for multiplayer, which means one of the players is also the host. So latency will always vary, based on who is hosting the match and how their network holds up/is used. So if your connection is fine there is not much more you can do.

                                        WTF dude are you running? Never seen even lan ping times that low..

                                        0.00003 seconds... Come on...

                                        Are you pinging the boxes own IP? That is not really a test of network latency..
                                        That is pfsense pinging itself.. Sure ok if that was high then something major wrong.. But that doesn't tell you how long it takes to get from pfsense to where your going and back ;)

                                        To PFSense

                                        I assume the actual latency is lower, but I see packetloss from the host CPU of the core router not able to keep up.

                                        You have to do ping floods to get really low measured latency because of CPU context switching. If you send one packet and block waiting, the kernel switching back to the thread takes a really long time relative to 1gb frame switching latency.

                                        Like this 154us standard ping

                                        Just look at this ping to localhost. It's nearly the same as targeting my gateway

                                        From what I can google, a context switch on a modern CPU is about 5us. Then you mix in the CPU trying to sleep and all that fun, you're left reading 200us.

                                          @grimson Definitely. I am convinced that any latency will be out of my hands for more than the simple reason that it is part of the internet and that depends on the game provider (netcode and latency compensation model), but also because i do not really have the know how for it.
                                          All i wish to know is when i am affected by higher latency so that i would leave a "bad" lobby for, possibly, a better one.
