"DiskSortOutputBlocksPercent" registry settings in Sagent Data Flow

Product Feature: DataFlow Server
This registry setting governs percentage of output blocks used for Disk Sort. Suppose there are 100 blocks set for DiskSort and "DiskSortOutputBlocksPercent" is set as 40. Then, these blocks get divided into 2 sets of the block, one is input block and another is output block.
The output block is 40 as  "DiskSortOutputBlocksPercent" is set as 40% and remaining is used as input block.
