Thanks for all the advice. I set up the 4GB RAM disk, verified it was putting Derived Data there, and tested against a dynamic framework I build often. I even rebooted to have a clean starting point.
The results were not great. The framework normally takes between 13 and 17 seconds to build, and the first try with the RAM disk took 19. After that it recorded some lower times, but essentially a minor improvement, if at all. A little surprising. Anyway, determined to stick with the 2013 machine for a while longer, it's still "good enough."
