Zenarmor (Sensei) / Sensei throughput cap despite high-performance device
« on: September 20, 2022, 04:26:17 am »
I am running OPNSense on a dedicated i7 CPU with 32 GB of memory and 6 gbps ports. Ubench CPU 1132791 and Ubench MEM 2337171. My internet connection is 1 gpbs.
Before installing and enabling Sensei, average throughput on fast.com or speedtest.com was close to 1.0 gbps with a usual overhead penalty. But when Sensei is installed and active on LAN ports (L3 mode with either native or generic nmap driver), throughput drops to 250 mbps - mere 25% of available bandwidth. CPU is idling and never goes above 15%.
I installed the new 20.7.3-netmap driver - but that didn't change the throughput at all.
What am I doing wrong? What troubleshooting data would you like to see?
