        If you are running at 10 Gbit/s uplink, do you use DirectPath I/O with the pNIC's to pfSense or do you virtualize them to pfSense?
        Otherwise the platform is a more current generation than mine.

          I dont see any issues at all related to high CPU on 2.0.2 release.

          Running 3 seperate FW's on 4.1 U3.

          Packages:

          File Manager
          Open VM-Tools 8.8.1
          PFBlocker
          Snort

            I am not. I only use 10Gbit internally and use the build-in 1Gbit for PF WAN.

            No directpath, but virtualized through VmWare.

            :)

            I am running the 32bit version of Pfsense and VM version 7.

            2vCPU and 1GB of memory. 11% memory used at the moment and 37% disk.

              Are people still having this issue with the latest esxi 5.1?

              I am running 4.1 at the moment and basically any sort of large download kills access to every VM running on the host until it is complete! :(

              I have tried everything I can think of and is listed on here, I am getting it on all versions of pfsense from 1.2.3 up to the latest.

              It has got to the point now, I am either going to have to setup Pfsense on some dedicated hardware or switch to monowall but I really need openvpn :(

              So is upgrading to esxi 5.1 a fix for this?

                Try to limit the download bandwidth. ;)

                Currently seeing ~2% CPU on the ESXi host on 2.0.3 REL.

                  I have tried that, even if I limit to 20 meg it still plays havoc :(

                  What version of ESX are you on?

                    4.1 U3.

                    Dont want to upgrade to 5.x since I dont need the new features in 5.x.

                      Looks like my only option is to move to hardware in that case :(

                          I know there are going to be vlans everywhere but what else can I do, I cant get any version of pfsense to play nice.

                              Yes I got exactly the same, the problem is as everyone is accessing the environment via ipsec tunnels or the ssl vpn all it takes is for one user to do a download and everyone's sessions jump about or die totally :(

                                        Can you test there to see if its a 5.x issue then?

                                        Rather keep it in a VM than on physical hardware for the flexibility :)

                                          Yeah I am willing to give that a go, but I need to drive a way to the DC to do the upgrade that's why I was asking if anyone had tried it, I didn't want a wasted trip :)
