> 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%.
