git plugin 4.4.0
Description
When performing a git clone operation,
git-client and git-plugin both triggers a git fetch.
Below are the two lines of code running in the same git clone command both doing fetches.
The second link is part of the GITSCM step, it triggers the git-client-plugin's CloneCommand (first link) to perform the clone operation. And afterwards, the GITSCM step performs a fetch once the CloneCommand Completes.
However, within the CloneCommand (first link) itself, a fetch command was already done.
I am aware there are needs to support for git clone to fetch all refs first -JENKINS-31393
Thanks,
Sam

dogin2006 you're welcome to propose a pull request to the plugin to improve its behavior. Alternately, you could try replacing the "depth=2" with a reference repository to see if that would reduce the fetch time.
Using a reference repository doesn't fix the issue.
Using the command line git clone including reference repository, it takes approx 11 seconds and the same configuration via the checkout scm option takes 1 minute 3x seconds.
I have attempted to fix this issue:
https://github.com/jenkinsci/git-plugin/pull/845
The fix from rishabhbudhouliya has been merged to the master branch and will be included in the next release of the git plugin

Using "${GERRIT_REFSPEC}" fix the first problem.

In our case, both fetch cost about one minute.
