Describe the bug
Running git lfs migrate import using version 3.0.2 is around 60 times slower compared to 3.0.1. Git repository with 5941 commits takes around 9 minutes to complete using version 3.0.1 and using 3.0.2 only managed to reach 60% of the commits in 6 hours of running.

To Reproduce
Steps to reproduce the behavior:

1. Download and install Git version 2.34.1 or 2.34.0 from https://github.com/git-for-windows/git/releases
2. Run git lfs migrate import --yes --include="..." on a Git repository
3. Download 3.0.1 version of Git LFS from https://github.com/git-lfs/git-lfs/releases/download/v3.0.1/git-lfs-windows-amd64-v3.0.1.zip
4. Apply the git-lfs.exe file on top of mingw64\bin\git-lfs.exe in the install location of Git
5. Repeat step 2 on a fresh Git repository

Expected behavior
Time taken for git lfs migrate import command to run should be identical with v3.0.1 and v3.0.2.

System environment
Windows 10 v1909

Additional context
This issue seems to be independent from Git version itself as I managed to reproduce the same issue with replacing the Git LFS delivered in Git versions 2.33.0, 2.33.1, 2.34.0 and 2.34.1 with versions 2.13.3, 3.0.1 or 3.0.2 of Git LFS and all Git versions are affected when using 3.0.2.
