Hello!

My problem is the high cpu usage on low traffic in pfSense 2.3.1
I use the pfSense as transparent firewall there are 2 vmbr nic.
I added 2 core cpu (2,9Ghz) and 2 E1000 nic.
The raffic is around 5MB/s and i have only 9 rules.
BUT the CPU usage is around 70% but minimum 50%.
Someone have any solution for it?

(I use the latest proxmox updates)
 
I use several PFSense 2.3.x in Proxmox and work very well.

-) Use only virtio network (and storage)
-) Disable hardware checksum offload (in PFSense)
-) Disable: Use tablet for pointer
-) Use fixed size memory (reduce cpu usage)
