I don't know what operating system you're talking about, but the bottleneck on my linux machine for asking for interfaces is the fact that stdout is write blocking.

I routinely have shy of 100 network interfaces active and `ip a` is able to query everything in nanoseconds.

Considering this whole conversation is about sometimes some people have a little bit of slowness drawing the quick settings area in Windows 11 and I gave commands like "netsh" it should be pretty dang obvious which OS we're talking about. But I guess some people have challenges with context clues.

And once again, on some Linux machines I've had over the years, doing an ip a command could hang or take a while if the device is in a bad state or being weird. It normally returns almost instantly, but sometimes has been slow to give me the information.
