Thanks, Raul. As Raul hints, /System/Applications/Utilities/System Information.app is normally launched by clicking the button: "System Report…" in "About This Mac". I already had this app residing in my Dock. Its display is dense, but the Hardware overview tab is brief enough, and shows the following info relevant to J performance:
Model Name: Mac mini Model Identifier: Macmini9,1 Chip: Apple M1 Total Number of Cores: 8 (4 performance and 4 efficiency) Memory: 8 GB I'll look-up how to fetch this data programmatically, and think about including some of it in JVERSION for iOS, following what Bill does for Android. The Apple M1 chip isn't the first and last for Apple. The new Mac Studio device: https://www.apple.com/uk/mac-studio/ has a choice of 2 new chips: M1 Max and M1 Ultra with some attractive properties. I'm sorry for taking this thread so far off-topic. But IMO the issues raised here are important ones for the actual performance of the new J parallel execution. But I'm not sure performance comparisons are best reported in this particular forum, except in summary form. I was only ad-hoc responding to comments by Henry and Bill. But it will be good to perform them, and make them available without having to pm the tester. How about the wiki, with links posted to JGeneral? Raul's FYI gives good guidance about what they should contain.
