pf Performance question

[Doug Hardie]

I have several devices that emit udp packets to a specific port every second. Unfortunately, they cannot terminate that. However, on my systems they show up in pftop and netstat. Currently I have them ignored in pf. They create state entries, but there is nothing listening to that port. Will it use less CPU if I put a pf drop statement for that port?

Honestly, if it's a single udp packet every second you have nothing to
worry about ... unless you're running hardware maybe from the 80's. ;)
