> There are some [improvements being made to CLHM| https://code.google.com/p/concurrentlinkedhashmap/source/detail?r=888ad7cebe5b509e5e713b00836f5df9f50baf32] that we should test.
> Create a small enough dataset that it can fit in memory and devise a test that has a high key cache hit rate, and compare results to CLHM 1.3 we already use.
