    I have seen that adjusting the aggressiveness of Gurobi's presolve routine may have a strong effect on Gurobi's performance with set covering problems.  To adjust this, you can change the Presolve parameter.

    Generally speaking, the MIPFocus parameter often has the largest impact on MIP problems because it changes the high-level solution strategy, depending on your goals.  To read more about this, check out the MIPFocus documentation.

    If the number of parameters that you can change gets a bit daunting, Gurobi does have an automatic tuning tool that you can try out: Parameter Tuning Tool.
