Description

The difference of startup times between a 0.8.7 cluster and 1.0.7 cluster with the same amount of data is 4x greater in 1.0.7.

It seems as though 1.0.7 loads the BloomFilter through a series of reading longs out in a multithreaded process while 0.8.7 reads the entire object.

Perhaps we should update the new BloomFilter to do reading in batch as well?
