> Using the LoadingCache with default builder settings. 100,000 TezTaskIDs are created in 10 seconds on my setup. With a LoadingCache initialCapacity of 10,000 they are created in 300 ms. With no LoadingCache, they are created in 10 ms. A test case in attached to illustrate the condition I would like to be sped up.
