I have built the following Firewall box : i3-4160, 8gb ram, 240gb 6g sata SSD, 4 port AOC-SGP-I4, Gigabyte Z97 LGA 1150 MB. I have GB internet (Cincinnati Bell FiOptics).
Using the simple firewall/router from CBT i get 670mbs/160mbs using CBT's test servers. With pfsense firewall 145mbs/135mbs, Sophos I get 140nbs/130mbs.
I was using the built in Intel GB nic and Intel desktop card. I upgraded to the AOC-SGP-i4 and gained barely 10%.
How or what can I do to get closer to the the straight router.
CPU - less then 5%, Ram less then 8%.
I turned off IPS/IDS and have a simple rule internal - Allow Any.
I should be able to get better throughput. If I use a Pan-200 device (Palo Alto Networks Firewall, I get 190mbs/120mbs (I turn off App and IPS/IDS).
I have tried the Home and Business versions.
