       | Uh oh.
       | 
       | Also, if you need that much memory in a firewall, its queues are
       | too big and you're adding substantial latency.

         | 
         | FWIW, I'm not using it as bare OS firewall. Instead, it's
         | running Debian with pfSense in a VM with 2 passthrough NICs
         | (though I'm considering replacing Debian with Proxmox).

         | 
         | Maybe it's stateful and you've got a whole lot of connections?
         | Or in this case, they're planning to run VMs and things on the
         | box, so might need more ram for that.

         | reverse proxies. Which can make very good use of ram.

       | I have a very similar unit from Protectli running an OpenWrt x86

       | home/small business.
       | 
       | It replaced an enterprise-grade Mikrotik router, which while no
       | doubt being more performant (it has hardware offload for
       | routing/firewall), was a pain to configure and certain scenarios
       | are almost impossible to implement (WAN failover where one of the
       | WAN interfaces is a PPPoE link) on it where as in OpenWrt they
       | work out of the box.
       | 
       | The lack of hardware offloading for firewall/routing doesn't seem
       | to be an issue in practice for gigabit links.

       | old netbook. Apparently it's semi modern though, and quite a bit
       | faster than the old wimpy atoms.

       | I like learning about the latest and greatest developments in
       | these compact, fanless router boxes. But, so many are only
       | available through seemingly random AliExpress sellers. Maybe this
       | is being overly cautious, but I would never trust my home and
       | small business networking duties to off-brand hardware like this.
       | I worry about poor QC, nonexistent customer support and
       | nonstandard/undocumented gotchas. This is not even considering
       | outright malicious behavior by one of these storefronts.
       | 
       | I've used Protectli and PC Engines boxes before, which have been
       | great. I'm definitely leaving some value/performance on the table
       | compared to the hardware described in this article. I also know
       | that Protectli hardware in particular is supposed to be identical
       | to some of the Aliexpress boxes, at a higher price. But at least
       | I have some assurance that the company behind the hardware has a
       | reputation at stake and will hopefully stand behind their
       | products.

       | I'm kinda skeptical, unless I'm missing something. How much time
       | does it take for a VM host to reboot and resume firewall guest vs
       | reboot firewall on metal?

         | Edit: I see you were referring to the host boot times plus the
         | VM boot times, which I am not and neither is the article.
