Feedback: nRF Connect Toolchain Manager download speed

[Chris Pearson]

This is just simple feedback on the nRF Connect Toolchain Manager v0.9.2.

The download speeds when installing an SDK are terribly slow. On a 1Gb/s connection my PC was only seeing ~160kb/s while the SDK was downloading. The total install time wasn't too unreasonable, but it "felt" slow.

If this is not due to issues with the SDK file server, I would suggest downloading the components of the SDK in parallel, and perhaps add a download accelerator library to it (should one exist for Electron.) 

As well, the status text suggests that various repositories are updated after the initial install. Perhaps these updates could also be done in parallel?

Cheers!

Also really struggling with this. V3.1.1 and has taken >3hrs so far to download the SDK via VS Code.

Hi Øyvind ,

I have logged a support ticket already and am waiting for support on it. 
Just adding to the above info to the thread for visibility as it does seem to be a recurring issue on a number of threads and forums, as the issue doesn't seem to be solved

Kind Regards,
Tristan

This still happened to me in April 2026, downloading the SDK and toolchain v3.2.4. I'm located in the US, and I was downloading through the VS Code nRF extensions for development there. It took multiple hours to download the first part at ~150 kB/sec, as above, and when the second part looked like it was going to do the same thing, I decided to turn on a VPN service I have with an exit node in Norway. Then the entire process finished in two minutes, downloading at around 20 MB/sec.

So, I don't know what the root cause is, but a VPN into Norway certainly did a good job working around it.

This also worked great for me, download took less than 5 minutes. Thanks!
