checkout after partial clone with git clone --depth 1 --filter=blob:none --no-checkout is extremelly slow when there are many files #1888
Description
Instantaneous (10k files small files):
git clone https://github.com/cirosantilli/test-github-many-issue-templates
Takes forever, seems to fetch one file at a time:
git clone --depth 1 --filter=blob:none --no-checkout https://github.com/cirosantilli/test-github-many-issue-templates
cd test-github-many-issue-templates
git checkout master -- .github/ISSUE_TEMPLATE
because you can see in the stdout files coming out one at a time every 0.5s:
remote: Enumerating objects: 1, done.

This makes partial clones unusable for most cases, even 100 files would be almost unbearable.
Tested with git version 2.27.0.
