I wonder what such a benchmark test would be good for.

Relevant and speaking tests in Global Optimization are formulated as models in AMPL, GAMS, GMPK, MPS, etc. Rewriting a model in matrix form can be a tedious manual task and I have not yet seen it.

Very few optimization packages in R accept such higher models as input, as for instance linprog, lpSolve, Rglpk, or Rsymphony.

And those that do are in reality free implementations that have been integrated into R. Benchmarking these functions will not show significant differences to benchmarks done with their original versions.

Did I misunderstand your intentions?
