@mihaip @siracusa (Where “better” is, like, “please murder my machine with 1200% CPU for 20 seconds because I want my Xcode now” rather than doing 400% for a minute. But even 400% from compression_tool is better than 100% from single-threaded zip)

@mihaip @siracusa oh ALSO because I cannot actually shut up I would like to mention (even though you might know more about this than I do) but there’s a bunch of other stuff that influences GUI operations. For example your compression will go faster if it’s in the foreground

@mihaip @siracusa Because macOS will throttle apps that are not visible and this includes their XPC services unless they opt out and I don’t think Archive Utility does. Also I seem to remember it sets like an iopolicy or something to have less of an impact on your system
