            I don´t think that KVM causes the problem. Maybe pfSense analyzes the packages and that causes the high load?

              What packages do you have installed?  Squid w/ICAP?

                  If you don't have any packages installed, then it definitely IS an issue with KVM, as the base product has pretty low CPU usage even at high throughputs.

                    The CPU load only increases when I download something. Are you sure, that KVM is the problem?

                      high cpu load is the symptom of of a VM Guest not interacting well with the host. PFSense runs fine at multi-gigabit speeds out of the box on desktop grade CPUs and decent NICs.

                        We're sure that it's not pfSense that is the problem.

                          Which Networkcard should I use in KVM for the pfSense VM?

                          VirtIO (Paravirtualized)
                          Realtek RTL8139
                          VMWare vmxnet3
