Title: Firewall throughput vs port to port firewall throughput?
Post by: shmerl on November 24, 2022, 01:46:13 am

Official Opnsense hardware like DEC750 lists two metrics: firewall throughput (10 Gbps for it) and firewall port to port throughput (8.5 Gbps for it). What exactly is the difference and what does it mean?

Firewall throughput is maximum aggregate throughput across all ports.

It's still not very clear.

Let's say I have such scenario:

* One 10 Gbps SFP+ on DEC750 is connected to WAN.
* Another 10 Gbps SFP+ port is connected to a switch (that supports 10 Gbps).

Some device is connected to that switch as well.

What would be the total throughput between that device and WAN if firewall is active?

8.5 Gbps. If you have another pair of of 10G ports the total throughput across all 4 ports will not exceed 10 Gbps.

All according to specs. In reality as always your mileage may vary.

I see, thanks.
