Firewall latency off the 6400 appliance.

[SaraDokaj]

Hello,

I am trying to find out if the firewall latency of the 6400 and 6400 plus appliance are less than 3 microseconds, but I can't seem to find any information in the datasheet. 

Can you please help me with that?

Thank you!

To be sure we're talking the same unit, a microsecond is 0.001 milliseconds, or 0.000001 seconds.

Even cut-through switching is generally around 5µs, and that's without any filtering.

Actual latency numbers depend on the precise configuration.
I don’t have the exact numbers offhand, but pretty sure it’s higher than that.
To get down to single digit microsecond latency, you’re basically in switching territory like @Bob_Zimmerman said.
