Have double verify that pigz will also install unpigz.

Thanks, just installing pigz would take care of parallel docker extraction? I'm curious why docker dont directly install it as pre-req. :)

Do we need this package on windows as well? To full the images faster?

It is already installed on Windows and reduced time from 15-20min to 12min 😄 https://github.com/opensearch-project/opensearch-ci/blob/main/packer/scripts/windows/scoop-install-commons-docker-support.ps1#L76-L87

Yes, there is a long history of thread to get pigz/unpigz support in docker. As of now, docker build is still single thread and docker pull/extraction can support unpigz if detected in path. The thing is docker maintainers seems still thinking parallelism can cause trouble between, thus not suggesting it by default. Thanks.
