Hi
I have been using an Intel X550-T2 NIC. As a test I switched if for a Chelsio T520-BT. I use a FreeBSD 12.0p3 firewall on a Xeon D Supermicro main board. I have over 500 firewall rules and 6 vlan:s. I have been able to push over 9 Gbit through it with just 8-10% cpu usage.
The Chelsio adapter was a real disappointment. The speed is 2 Gbit lower in the same test and the CPU i 50% over all four cores during the tests, i.e much higher CPU usage taken by interrupts. I have also tried to tune the Chelsio card according to Olivier Cochard-Labbé:s paper for tuning FreeBSD firewalls.
The intel card is simply a much better card!
I post here to ask if someone is sitting on some hidden secrets that can prove otherwise..
Thanks
