Benchmarks

Map benchmarks

Everybody have different goals when benching against others.

This one is no exception: the aim was to test speed consistency against different kinds of inputs, rather than peak performance on favorable conditions. (which is Random keys for hash-based containers) Object benchmark tried to stress on that, by trying to simulate a heavy cost for equals()/hashCode(), so tend to favor the implementations where the number of calls for put()/get()/containsKey() are minimal.

Benchmarks are perfomed against Koloboke 0.6.7, Fastutil 7+, GS collections 6.2:
