Slight tangent. We should test out LongAdder for connection pool
stats at some point. It should make a significant perf difference.
Yes, I would like to bring this in for all the stats, so they have the least amount of
impact when they are on. I understand Infinispan is already using it, but we had to turn
off their stats too to get the best second-level cache performance (made a big difference
even with LongAdder).
