Do you solve your lp with the exact solver from the very beginning?
If so, do not do that. Solve the lp to optimality with the ordinary
floating-point solver and only then call the exact solver. This
prevents performing most of simplex iterations in exact arithmetic
and may significantly reduce the solution time.
