AcesShared agents download the default 64 KB chunks of the ~1.5 GB macOS
node_modules archive at ~7 MB/s, with blob request timeouts, so each macOS
job spends ~3.5 min restoring it. Pipeline artifacts with 1 MB chunks reach
~40 MB/s on the same agents. Set the agent's chunk size knobs on the Cache@2
steps so their post-job step saves new entries with 1 MB chunks, and add a
key segment so new entries are created in that format.
