We need to verify that this is still a problem with the parboiled transformer parsing in 2.0. Andrew Hulbert can you take a look?

Research direction

Start by locating the converter's recursive field-dependency calculation and the parboiled transformer parsing in version 2.0. Reproduce the slowdown with hundreds of dependent fields, then verify that the calculation is acceptably faster without changing dependency results.
