Although the author is an Electrical Engineer he got interested in optimization problems using the GAMS software. Rapidly he understood the limitations of the nonlinear solvers, like the necessity to have an initial feasible solution and the high probability of the solver being trapped in a local optimum and since 2004 he solved a set of complex nonlinear problems using MILP models.

Integer programming is NP-complete. In particular, the special case of 0-1 integer linear programming, in which unknowns are binary, and only the restrictions must be satisfied, is one of Karp's 21 NP-complete problems. If some decision variables are not discrete the problem is known as a mixed-integer programming problem.

Both of these solvers are roughly 10x faster than any open source MILP solver. Changing your solver is probably the fastest way to achieve some sort of speed-up. In addition, you could look to see if you could reformulate your problem so that the LP relaxations are tighter, or introduce more and better cuts that exclude nonintegral regions of your feasible region.
