Track Brian Kent's issue.
Comparing CASA-5 and CASA-6 across the two different CPUs available for batch processing in NM and CV shows that the newer CPUs (E5-2640v3) run a simple calibration job (6.7GB) about 1.25 times faster than the old CPUs (E5-2670) with CASA-6 performing slower in every case.

Running just hifv_importdata() on a larger data set (350GB) shows that nmpost nodes run about 2% to 10% faster than similar cvpost nodes with CASA-6 performing slower in every case.
