i've seen this for years in opnsense. it doesn't matter if it's a xeon or an atom..interface changes can take between 10-30 seconds to apply. I have noticed this on pfsense as well. Is this a BSD thing? There's not a linux firewall i've ever used that takes this long to apply interface changes. Any BSD based firewall though takes this inordinate amount of time to apply interfaces changes. I am curious what is going on to introduce this excessive and apparently endemic lag in interface change application.
