Benedict commented on CASSANDRA-6934:
-------------------------------------
I decided to put in some of the extra optimisations now after all - whenever
the clustering/ordering components of a type all support unsigned comparison we
now avoid almost all virtual method calls. This gives a 10-20% bump in some
very quick and dirty tests on my box versus the prior optimisation, and
probably has a larger effect on clustering columns (which still can't easily be
benchmarked, but I will fix that next week)
> Optimise Byte + CellName comparisons

> AbstractCompositeType is called a lot, so deserves some heavy optimisation.
> SimpleCellNameType can be optimised easily, but should explore other
> potential optimisations.
