When you pass a parameter, your sending an object already in memory to the microflow. With a retrieve, you are getting an object that is not currently in memory and placing it in memory. While the resulting object may be the same, retrieves require more work on the part of your app.
Does that answer your question?

Hello Mike, Thank for the quick response! Well yes, but if you set the retrieve "by association" wouldn't it also be retrieved "by memory"? Or am I looking at it the wrong way?
