 Conservation law elimination is not expected to ever impact performance negatively; it simply results in a (possibly) lower-dimensional system of ODEs to solve. However, eliminating conserved species may have minimal performance benefits; it is model-dependent whether elimination results in faster ODE solving times and/or increased solution accuracy.
