What is a "normal" interupts rate
We are running pfsense 2 as a router for our cloud.
The servers are Dell with broadcom nics (bce).
We pass average rate of ~ 40Mbs.
When we run top, we see ~ 15% interupts rate.
Is this normal?
Depends on traffic rate in pps not Mbps, and the hardware you have. That sounds roughly normal depending on specifics.
