> Many in-core performance optimization opportunities exist in zebra, such as
> removal of redundant precautionary checks, use of better collection types to
> reduce levels of indirection to the memory objects, changing of input splits
> in ascending sizes to descending sizes. Observed improvements of wall clock
> time of some PIG LOAD queries are around 10%.
