Benedict commented on CASSANDRA-9988:
-------------------------------------
Before committing, you may want to consider modifying the microbenchmark to use
objects that are of a representative complexity, and over a large enough domain
that the contents will not all be in the processor cache. This might affect
the choice of exponential search vs. binary search, as the extra comparisons
needed are not currently representatively counted.

> In many cases we have small btrees, small enough to fit in a single leaf
> page. In this case it _may_ be more efficient to specialise our iterator.
