GPLK vs Gurobi speed on simple MIPs

The solve times on my machine for a single model are ~4ms for Gurobi and 1.5ms for GLPK.

I’ve often found that Gurobi is slower than CPLEX/GLPK on small models. This is because Gurobi does most of their performance benchmarking on “hard” MIP instances which take > 100 seconds to solve. In practice, no customer is complaining about a MIP taking an extra 2ms to solve.
