      Possibly not 100% correct, but the nics might be these:

      ath0 - Atheros Communications Inc. - AR5212, AR5213 802.11a/b/g Wireless Adapter
      or 
      ath0 - Atheros Communications Inc. - 802.11a/b/g Wireless Adapter (AR2312)
      
      dco - Davicom Semiconductor Inc. - 10/100 Mbps Fast Ethernet Controller (DM9102/A/AF)
      
      fxp0 - Intel Corporation - 82801DB PRO/100 VE (LOM) Ethernet Controller
      
      fxp1 - Intel Corporation - 82550/1/7/8/9 EtherExpress PRO/100(B) Ethernet Adapter

        Is there a way to know if Intel cards have a problem with pfsense

        With the latest version Anyhow

          Just to clarify this, there is not any known bug in the Intel driver or card setup (that I know about at least). I mentioned this only because the symptoms described were very similar to those I had been reading about in another thread.

          https://forum.pfsense.org/index.php?topic=74942.0

          In that instance the high latency was seemingly solved by removing the loader.conf.local setting limiting igb to 1 queue.

            I know I understood it the first time
            My questions were just to rule out a network card problem

            What could it be
            why is the  latency go crazy
            from 10 to 300
            why all internet browsing so slow
            Except from the upgrades i did not changed anything

              OK. I just wanted to be sure I hadn't mislead anyone.
              Your interfaces all appear to be older cards, 2 fxp NICs and one dc. Are you seeing latency problems across all of them?
              The driver changes I was talking about were for the newer Intel drivers (em. igb, ixgb) for gigabit NICs and they went into 2.1.1. I don't beleive there were any driver changes between 2.1.1 and 2.1.2.

              @firefox:

              The temperature of the CPU is also higher than normal

              This would indicate that the CPU is working hard on something which could be causing the latency. What do you see if you run 'top -SH'?

                Currently the temperature is about 53 ° C
                and latency 18
                It reached 56 ° C

                Before the upgrade it was from 30 to 36 maybe 40 in an exceptional case
                And the latency Was up to 30 maximum

                  If you run it from the console you will see the line detailing how the usage breaks down, like this:

                  You have more than twice the processes I do, though I'm not running many packages on the above box.

                  A couple of things that have caused similar symptoms in the past come to mind. If you have any sort of CPU frequency scaling enabled and it's not quick enough responding to the load it cam start to appear like a large load. Doesn't really explain why it's running hot though.
                  The other thing is ASPM which can cause problems similar to this. Not sure if that's PCIe only though. Worth checking if it's an option in your BIOS and disabling it if it's there.

                    @ESPNSTI:

                    pciconf -lv
                    

                    It won't spell out the nic brand or model, you'll probably need to Google the chip number.

                    I always add the file that pciconf can use to translate device ids to descriptive device names on all my pfsense installs so that the list is much easier to read.  I really wish pfsense would include that file by default.  It is very useful but it is about 400 KBytes.

                    /usr/share/misc/pci_vendors

                    I just do a search for that file for whatever version of freebsd pfsense is running and manually put it in place.  pciconf is so much easier to read after that.

                    This…

                    
                    em2@pci0:4:0:0:	class=0x020000 card=0x060a15d9 chip=0x10d38086 rev=0x00 hdr=0x00
                        class      = network
                        subclass   = ethernet
                    
                    

                    becomes this…

                    
                    em2@pci0:4:0:0:	class=0x020000 card=0x060a15d9 chip=0x10d38086 rev=0x00 hdr=0x00
                        vendor     = 'Intel Corporation'
                        device     = 'Intel 82574L Gigabit Ethernet Controller (82574L)'
                        class      = network
                        subclass   = ethernet

                      The other thing is ASPM which can cause problems similar to this

                      I do not have this Option
                      I checked

                      now the latency in 325
                      Heat 50 °

                      Could be something on the network makes this
                      Perhaps improper connection of the network jack
                      Or improper cable

                      Do not know what to check

                        If it were a hardware problem I would expect to see a load of errors in Ststus: Interfaces:

                        You aren't seeing a high interrupt load then if you run 'top -SH' at the console (or via ssh)?

                            If you look at my output from top -SH above I have an extra line the breaks down the usage by type. If you run it fro the console, rather then via the webgui, and allow it to go a few cycles you'll see that. It probably doesn't contain anything useful but at this point it's worth checking anything.  :)

                                Nothing much there.
                                Kind of out of ideas here but I did notice that you are using some swap. That can cause serious performance issues. I wonder if a Snort rule update has pushed you over the limit of RAM and started swapping. Check your memory RRD graph to see if ran out of free memory at any point.

                                  I will check this with the snort Off
                                  But i do not think that is the problem
                                  it worked fine until now includes updates once a month

                                  Maybe the new version a bit heavy for this computer

                                    now problem is pfsense is working fine without squid but when i install and configure squid+squidGuard Transparent then it's given very slow browsing so please tell me the best configuration of squid for 90 users.
