Should this be reported as a bug or is it to be expected with RC? [image]

It seems that you are still using the old (slow) Git-based registry download. Try this maybe? [image] Pkg.update in Julia 1.5 uses github General Usage You probably have the General registry as a git repo. Delete it and install it again.

Unfortunately, I have to confirm that it sometimes takes forever to download the registry on Windows. I’ve observed this even on a fresh machine with no previous local (git) registry and also when setting ENV["JULIA_PKG_SERVER] = "" and so on. Internet connection was fine and can’t explain the behav…

Just to contribute more substantial evidence to the discussion: [julia_slow] I tried to make the gif match “real time”. It hangs at 99,9% for about 2 minutes. This is Julia 1.6 on windows 10 with no prior Julia installation (i.e. no ~/.julia directory). (BTW, I don’t think it is 1.6 specific. I a…

I nuked my registries (on 1.5 and 1.6) and tried again. Same results here. The initial installation takes ages.

Check if Windows Defender is taking a lot of CPU.

[julia_faster] Indeed, turning off Windows Defender reduces the time quite noticably to about 30 seconds. I would still say that it could be faster (it is on macOS) but it is probably acceptable like this. So I guess the question is how to avoid the chiming in of Windows Defender. (BTW, Windows De…

I have ~/.julia/ added as an exception in Windows Defender.

What will probably happen is that files will be read straight out of the tar ball downloaded (see Tar.extract_file: extract content of single file in tarball by fredrikekre · Pull Request #95 · JuliaIO/Tar.jl · GitHub ) which would avoid having to materialize so many files (which is what causes Windo…

Thanks for the suggestion! Just to verify - is this the same as “Add an exclusion to Windows Security” described here ?

I have the same problem with Julia 1.7.2 on linux. It eventually works after spending about 2 min at Fetching…99.9%

Pkg fetching takes very long at 99.9% @ v1.6 (Win 10)
