Ferdinand Xu commented on PARQUET-41:
-------------------------------------

Thanks [~jbapple] for the suggestions.

As a result, I have seen speedups of 50% to 500% (depending on the operation 
and filter size) over the fastest other general-purpose Bloom filter I know of.

Is there any benchmark or reference about this number?
