More on network models (2)

What if you go bigger? Here some results with two of the leading commercial LP solvers (using default settings) compared to GAMS:

LP solution times are a little bit more unpredictable (in this case this is positive: somewhat quicker than thought by extrapolating from first picture in more-on-network-models.html), but GAMS execution time (including generation time) is still nicely linear.
