Huh? Koloboke's implementation jar is *larger* than fastutil's! Check on Maven
Central.
In the typical range of sparse vectors, fastutil is also slightly faster.
tests.maptests.prim_object.FastUtilIntObjectMapTest (10000) = 796.4631357999999
tests.maptests.prim_object.HftcIntObjectMapTest (10000) = 901.6948074
tests.maptests.prim_object.FastUtilIntObjectMapTest (100000) = 1109.0534656
tests.maptests.prim_object.HftcIntObjectMapTest (100000) = 1172.1181604
(This are get() calls on int -> Object maps, performance on int -> doubles will
be equivalent).
The difference might vanish soon though, as after the java-performance.info
tests everybody is looking at everybody else's code.
