I wrote a Shortcuts subroutine which is a text processing filter. It scans an XML config file for a Firebrick 2700/2900 and converts it into legal XML for an FB2500 (which has no USB port in it for a 3G/4G USB ‘dongle’ NIC.) Running it on a real XML config file is painfully slow, taking many minutes - I lost count, bored. It isn’t loading the CPU up fully; only something like 20-25% according to a system status app that I have.
I wondered about trying it on my wife’s iPad Pro v3, which is double the speed (on one core) of my iPad Po v1, and quadruple if all cores are utilised. But I don’t know how to copy a Shortcuts program onto another machine. But I’m not sure there’s any point if the thing isn’t correctly CPU-bound, as it should be.
Any idea what might be going on? I’m wondering if this is a badness in iOS 14’s new version of Shortcuts, which has had massive changes, all for the good, apart from possibly this and a display layout change to proportional fronts that means that existing programs’ layout is now all screwed up.
I sent in a bug report to Apple. This has to be worthy of one.
