Why is my pfSense Firewall Lagging and Giving 504 Gateway Timeout Errors?

But should pinging 60 interfaces really be this difficult for pfSense?

Wow .. 60.
A small script file that send a ping packet every ... not sure, 250 ms or so, and even 60 of them, that's no big deal.
But when one, or more of them get triggered because the interface and/or isn't there anymore ... dpinger will take action : it will reset (like pull down == destroy and pull up == recreate) the connection.
And now for the fun part : this will have a cascade effect on other processes, like nginx and unbound, just to name two of them, that will also get restarted. I've this 'feeling' that the 'mess' this creates goes up exponentially.
Your router is lagging, spikes to 100 % core usage etc ? I'm not very surprised.

I don't have the hands on experience, as I'm just a "2 WAN and 4 LAN ports guy", but If I had to 60 interconnections , 60 interfaces to manage, I wouldn't take that "Swiss Army Knife" firewall router called pfSense, but something more bare bone like TNSR ?
