And yet doing an ipconfig or netsh wlan show interfaces isn't always instantaneous depending on your hardware and the rest of your configuration. I can't tell you what all it's actually doing under the hood, but I've definitely seen variations of performance on different hardware.

Sometimes the devices and drivers just suck. Sometimes it's not the software's fault it's running at 43fps.

I'm hitting the little quick settings area on my exceptionally cheap and old personal laptop. I haven't experienced that slowness once. Once again I imagine the other stuff running interrupting all the OS calls and what not loading this information causes it to be slow.

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.
