nmittler 7aac50a79a Optimizing KObjectHashMap hashIndex() Motivation: The IntObjectHashMap benchmarks show the Agrona collections to be faster on put, lookup, and remove. One major difference is that we're using 2 modulus operations each time we increment the position index while iterating. Agrona uses a mask instead. Modifications: Modified the KObjectHashMap to use masking rather than modulus when wrapping the position index. This requires that the capacity be a power of 2. Result: Improved performance of IntObjectHashMap.	2015-04-16 10:27:17 -07:00

nmittler 7aac50a79a Optimizing KObjectHashMap hashIndex()

Motivation:

The IntObjectHashMap benchmarks show the Agrona collections to be faster on put, lookup, and remove. One major difference is that we're using 2 modulus operations each time we increment the position index while iterating.  Agrona uses a mask instead.

Modifications:

Modified the KObjectHashMap to use masking rather than modulus when wrapping the position index. This requires that the capacity be a power of 2.

Result:

Improved performance of IntObjectHashMap.
