nrfutil pkg extreemly slow on mac

[Hjalmar]

Hi,

using nrfutil pkg to generate the settings.hex file for the DFU is exceptionally slow on my M2.

I'm using what I believe is the latest version 

nrfutil 7.5.0 (063f665 2023-05-11)
commit-hash: 063f665c8ef5e4d46167077b52d39cf4e66ca24f
commit-date: 2023-05-11
host: aarch64-apple-darwin
build-timestamp: 2023-05-11T07:48:35.836017Z
classification: nrf-external

Is this expected?

Is this the latest version?

Running it on linux it's a couple hundred ms to finish, where on osx it's 15 seconds.

We might have seen this behavior with few other users on Mac. Can you try to test this again in offline mode not connected to the internet. There might be an issue with nrfutil trying to connect to some server or the firewall on your Mac trying to obstruct its access. The 15 seconds sounds like a timeout for such server connection attempts timeout.

Hi, Thanks for the reply.

No, that didn't make any difference. Just doing this:

hjalmarnilsson@Mac-Studio LCA1000 % nrfutil pkg
Usage: pc_nrfutil_legacy_v6.1.7 pkg [OPTIONS] COMMAND [ARGS]...

This set of commands supports Nordic DFU package generation.

Options:
--help Show this message and exit.

Commands:
display Display the contents of a .zip package file.
generate Generate a zip file for performing DFU.

takes 15 sec in the terminal

If there is no antivirus or any admin rule on your Macbook to scan every file/script that runs, and you have the latest, then we do not know what the issue is. We test these packages on Mac and have not seen this ourselves.I am out of ideas here.

Hi, tried this on two other mac Ms here (one M1 and another M2) and both show the same symptoms, my Intel mac doesn't have this issue. Do you test on arm M cores as well?

Is there any way I can get more logs out of this to try to pin point it?

[Hjalmar]

We have tried this on 13.6 and 14.6.

We still do not know why this is so slow. Are you running this on memory stick? Can't seem to understand what can make it this slow. I have some older Mac laptops which I will use to reproduce this issue next week.

[Hjalmar]

What do you mean running off memory stick? the OS? No, we are running this on 6 month old M2  mac studios. You don't need an old mac to replicate this!

Do you mean that you have a mac, where you can do : "time nrfutil pkg" and it takes sub 9 seconds?

I have now tested 6 different macs, and only one intel mac with an old nrfutil is quicker than that.

Also, the delay is even if the program isn't even feed with arguments, I've clearly explained above.
The "nrfutil pgk" will only display it's help, why does that take 15 seconds?

[Susheel Nuguru]

I am testing this today on few of Macs, If the delay is same at my end. I will do this test right away.
