PfS 2.3.1 with KVM (proxmox)
I got a problem with the CPU usage. I installed a simply amd64 pfsense (latest) and i setup as a transparent firewall the functions works fine but the CPU usage is HUGE i added 2 core and it use 80% of it. But the traffic only 3MB/s.
So what can i do now? I read much trick here but do not works. :/
Try using the virtio driver, this will help a lot.
On your proxmox use the virtio driver.
PS! It's still a lot more CPU consuming , compared to running linux under kvm.
