By far the fastest primitive hashmap implementation I found is https://github.com/leventov/Koloboke. It only contains maps and sets, and the original website is down, but the code quality is still there.
from elastiknn.
Another library maybe worth trying: https://github.com/real-logic/agrona/blob/master/agrona/src/main/java/org/agrona/collections/Int2IntCounterMap.java
from elastiknn.
Closing as it falls under #160
