Anyone have any completely non-scientific benchmarks <CNSBM> on the
difference between 7.1 and 7.2 index building? The new indexes are
supposed to be O(n) to make, while the old ones were O(n^2). So in
theory, building them should be noticably faster on large datasets.
Retrieval speed should not have changed radically...
