If both master and slave are set up identically, then theoretically
they should be identical, but if you ever optimized/analyzed one side
and not the other, or there were somehow two updates that got applied
to the slave in a different order from the master, the indexes could
have a completely different physical layout, while remaining logically
identical for the purposes of record lookup.
It could even be as simple as a "last-updated" timestamp in the index
header, or some bit of uninitialized data in an unused index block
causing your difference.
