The origin server might be set up to serve everything through cgi. That would mean loading the entire framework just to spit out a 404 for the favicon. If all the other pages cache just fine, you could hit 100% load on favicons when you'd otherwise be at 10%.

It's not an ideal design but I wouldn't call it 'horrible'.

What is CGI in this context? I’ve only heard of it in a movie special effects context.

The web server having to run an external program to handle the request, typically because it's written in a scripting language.

Technically it stands for "common gateway interface" but that doesn't come up very much.
