Thank you @matpil. This delay could be caused by a variety of things, like a slow network connection, or a slow authentication go git.

Do you see the same behavior if let's say you clone / pull a public repo, like https://github.com/microsoft/WSL ?

matpil commented

Hi,
If I clone a public repo (the same you suggest) the response time is ok

To connect to our git server I use a ssh connection (by sshkey)

btw, I feel to exclude a slow network connection; I don't know how to test a slow auth (as I said, it's by sshkey)

have you any suggest?

OneBlue commented

Thank you for confirming @matpil.

The fact that cloning a public repository doesn't reproduce the issue shows the performance problem doesn't come from WSL, so I'll close this issue.

Here are a couple ideas to help you root cause the issue:

  • Look into whether you have configured git credential manager on WSL, and see if removing it solves the issue

  • Try to run strace -f git pull and see where the time is spent

  • Check if your ~/.ssh/config has ForwardArgent or ForwardX11, and try to remove those options
