Unshallow Repository takes very long time

[dalia ezzat]

on one of our pipelines, fetching materials takes very long time, while observing pipeline, most of the time consumed in step "Unshallowing repository"

Any idea why this is happening ? and how to avoid it ?

[GIT] Performing git gc

[GIT] Unshallowing repository with depth 100

[GIT] Reset working directory

[GIT] Cleaning all unversioned files in working copy

[GIT] Cleaning submodule configurations in .git/config

[GIT] Updating working copy to revision...
