Description

JMH tests for parallel HT load, configuration parameters include LOAD_THREADS_NUM, ROWS_NUM and JOIN_TYPE.
A single thread simulates the default load behaviour while ROWS_NUM < 1M will default to a single thread for simplicity.
Higher number of threads >=2 evaluates the benefit of parallel loading of the HT.
