It’s got to the point where I turn off my WiFi now to do performance-sensitive work, because of the boost that killing all this background rubbish gives. Anything I need online I can just offload to my phone while my computer is offline.

The problem with doing that, is that the standard TCP timeout is 60 seconds.

All of a sudden, you are beset with 60-second hangs.

    If the computer doesn't have any online network connection, shouldn't it outright error? I understand that the timeout sucks when your network is not connected to the internet but still alive, then that's an issue, but if there is no connection at all, why would the timeouts matter?

      It wouldn't be able to open a TCP connection without knowing what IP address / interface to use.

      You're right--it should outright error. You should only see timeouts like that if you were dropping the packets from some middleware or middlebox, but your client still had a valid IP address.

    Just a wrap-up.

    It was a badly-written comment. I meant some apps (and background tasks) on my computer hang. Most deal with it, but a surprising number don’t. I gave up on sniffing with Terminal and other tools, trying to figure out which ones. I have a number of dev tools installed on my computer, and a lot of those have a … casual … approach to quality.

    I have no issue admitting fault (I do it way too often), but I don’t really dig rewarding boorish behavior, so I just figured I’d leave it alone.

    You just gave me flashbacks of mistyping a folder share name on windows and having the whole PC lock up for a minute or two.

    No, that's not how it works. Frankly, I'm astonished to see this claim here.

      The problem with this is some apps do incredibly stupid things. Now I'm not saying the operating system itself, but I had some ide screw off and go into long pause mode when my laptop was in airplane mode.
