If you are in charge of CI infrastructure that needs to perform frequent full clones of kernel trees from git.kernel.org, we strongly recommend that you use the git bundles we provide instead of performing a full clone directly from git repositories.

It is better for you, because downloading the bundle from CDN is probably going to be much faster for you than cloning from our frontends due to the CDN being more local. You can even copy the bundle to a fileserver on your local infrastructure and save a lot of repeated external traffic.

It is better for us, because if you first clone from the bundle, you only need to fetch a handful of newer objects directly from git.kernel.org frontends. This not only uses an order of magnitude less bandwidth, but also results in a much smaller memory footprint on our systems -- git daemon needs a lot of RAM when serving full clones of linux repositories.

Here is a simple script that will help you automate the process of first downloading the git bundle and then fetching the newer objects:

• linux-bundle-clone

Thank you for helping us keep our systems fast and accessible to all.
