So as far as the numbers go, the earlier one with 15 millions files still
holds. Wall time for that drops from 2 hours to 30 mins.


The other test I ran was running fsck on a freshly formatted 5OTB volume.
The wall time here reduced from 10 mins to 15 secs. The reason why it was
slower before was that the allocators were being read in an in-optimised
manner.
