I ran the command directly on my Macos 12.4 laptop and it took about 20 seconds to generate the entire listing.

Is there specific information you are looking to obtain?  You may be able to narrow the scope of the request and generate it faster.

happened, but if it is not LC then it must be an issue of one of the latest

Has anybody any idea, if I can optimize anything in the performance of this

could workaround, or do I have to take this shell call as it is?

Thanks for any ideas
