FreeBSD is not a switch. Bridging is done in software, so depending on your CPU the resulting bandwidth will be lower than your interface speed. There have been improvements in FreeBSD 13, but for anything beyond 1G I would recommend using a real switch.

oh i get it, im using an i5-4570T low power cpu, when i ran those 2 speed test, cpu usage increase to around 70%, maybe if i get an i7 with more power you think network performance will increase?

is there another way to take advantage of the 10gbps nics?

Hardware and Performance / Bridge bandwidth shared?

Hi everyone, I just installed an opnsense firewall on a supermicro server with 6 10gbps nics
https://www.ebay.com/itm/175222506227

I added a 1gbps nic for WAN and bridge all 6 10gbps ports together as documentation and tutorials says.

Everything is working "fine" but I did a few iperf3 tests and I saw my bridge bandwidht being shared.

I mean, I have 4 servers with 1gbps nics connected directly to each 10gbps port in the bridge.

When I do one iperf3 test between server 1 and server 2 it runs at almost 1gbps, but when I start a second iperf3 test between server 3 and server 4, both tests goes down to around 500mbps.

Why is this happening, shouldnt it have to work as a virtual direct link between the 2 ports so it may run at full speed (1gbps in this case)?

What can i be missing?

I will be upgrading server's nics to 2.5gbps soon, before going to 10gbps, but i would like to solve this issue first.

Thanks for any tips you can provide!
