While setting up the Parallelism in SSIS it is widely accepted that the total number of concurrently running executable will be No. of Logical/Physical processors+ 2, but no one explains how can we parallely run 2 more executable with the available processors.
Could someone please explain the presence of these 2 extra virtual processors that are available for use?
Thanks in advance.
