Picture syncing the full RKE2 manifest into a Hauler store: five files and seventy hardened images, close to ten gigabytes of content, over a link that tops out around 500 Mbps because that's what the environment gives you.

In Hauler 2.0, that sync pulled one image at a time. Image one finishes, image two starts, and the network sits idle between every handoff. On a large manifest over a slow uplink, that idle time is most of the wall-clock time.
