walters added a new comment to an issue you are following: `` It's [in the docs](https://ostree.readthedocs.io/en/latest/manual/buildsystem-and-repos/)
This is because OSTree has to re-checksum and recompress the content each time it's committed. (Most of the CPU time is spent in compression which gets thrown away if the content turns out to be already stored).
