Erase .julia. Activate and instantiate an environment. Windows 10:126 seconds WSL2: 13 seconds Is there a solution?

Have you benchmarked like, native Linux (for instance) on your machine? Those times don’t seem wild to me. I think it has a lot to download, no?

OH! Sorry I’m not reading properly.

For me the times on Windows 10 are also bad, especially because this also happens whenever the registry has to be updated, which is during most pkg operations. I saw the older thread where the new pkg protocol was mentioned (but it’s not better on 1.5 or 1.6 which should use that) or the windows def…

It is the General/registry unpacking (untarring) which is really long, as NTFS seems to take a very long time to recreate each directory (A, B, … Z)

Check the activity of the antivirus. The default windows anitvirus is going crazy everytime I add a package. I tried adding the .julia folder to the exception list but it still scans it.

There’s been two problems I’ve seen: When using git, the antivitus slows things down a lot When using the tar system, the untarring takes a lot of time. I believe the plan is to read things directly from the tarball without explicitly unpacking it which should hopefully fix it.

I did that, time is exactly the same when I add .julia/registries to Windows Defender exceptions … may be it is not really deactivated, or maybe (what I tought after this experiment) it is really the untarring which is very long. It seems that the “update” of General is really a full download/rein…

By the way I am not using the “git update”, but the new protocol (I did a “registry rm General; registry add General” just when I installed 1.5.1)

You can temporarily set the Windows defender of (I do this all the time. It resets itself after one day) [image]
