Benedict commented on CASSANDRA-8988:
-------------------------------------
I've pushed another branch
[here|https://github.com/belliottsmith/cassandra/tree/8988] which applies one
more optimisation, cutting the number of comparisons down by on average a half
lg(N) comparisons per operation, and also removing the boiler plate for
wrapping a Comparator, since we never use it. The JVM should optimise away the
inefficiency, but there's no point retaining it.
