There was not supposed to be. The intention was to do the minimal number of changes to allow the same results to occur in ITKv4 instead of ITKv3. No new features or changes were specified.
Ali did this work, so he will need to double check, but upon quick review it looks like a simple refactoring from one framework to the other.

Also I have found apple Instruments easy for diagnosing this bottle neck. This is one possibility among many. Good luck tracking down the issue.

The test was passed successfully in both release and debug types, and it took: 22 second in release 88 second in debug 2) I built NAMICExternalProject on my system in release type and ran the above BSpline test in BRAINSTools. The test was passed successfully again, but the run time in ITKv4 is tremendously longer than the time that test takes in ITKv3. The test took: 18 minutes using 4 cores 22 minutes using 1 core (In this case the environmental variable "NSLOTS" is set to 1). ================================== Basically trying to replicate in ITKv4 the same registration processes of ITKv3.
