Thanks for the answer.

We use also Opnsense on a Old Sophos SG330 and the perf are Better. (Without LRO/TSO: 6Gbps without jumbo frame) ands  with 2 Host 9Gbps!

Good to know that this Old Hardware are Bad!

Hello,

I need to install Opnsense on DL380 Gen8 (2*Xeon 2420/128Gb Memory)

But i have some performance problem with 10Gb Network.

Tested with 10Gb Intel 82599ES  and Broadcom 57810 (For every test)

Test 1 :

Opnsense directly on the serveur: Bad Perf with or without TSO/LRO...  <1Gbps
FreeBsd 13.1 directly: 9.2Gbps

Test2 with Proxmox and virtual Machine:

Opnsense: Bad Perf with or without TSO/LRO...  <1Gbps
FreeBsd 13: 9Gbps

Test3 Vmware (12Vcpu + 32Gb RAM) :

FreeBsd 13: 9Gbps

Opnsense: Bad Perf without TSO/LRO...  <1Gbps

Opnsense: with TSO&LRO... 8Gbps Youhouuu... (Iperf show some retry)

But after install of Zenarmor: 300Mbps.... (I suppose that the problem is the LRO/

Someone have already this case ?

Big thanks for your Help!
