By ghalliday:

I'm not sure. Yes if this is the only active sort in the graph, and if no other cpu intensive activities are going on. I'm not convinced that is likely to be true for roxie.
Also, the benefit of the parallel sorting only tends to come in for large sorts, and roxie tends to be sorting small quantities of data.
There should probably be a hint which could be used to enable the parallel sorting.
