Interesting. I'll do some test on NSAppleScript vs. osascript. I've been using NSAppleScript since forever and never had any problems. But you guys have way more experience with Alfred than I have.
I read about the speed in Monterey, too. I did a test with an Outlook script to get emails. My iMac from 2018 is faster than then M1 MacBook Air. Doing the script 1000 times was about the same speed. Oh, the iMac is on High Sierra and the Air is on 12.1 beta.
