with cplex, solver_io='python' is much slower than executable=(solver_path)

With cplex, when the model is large, the method of solver_io='python' is much slower than executable=(solver_path) . When the model is small, the method of solver_io='python' is the same as than executable=(solver_path) .
I would know how about this problem, and why the difference happen

The version of my pyomo is 5.6.6, the version of my pyomo is 12.9

This is a duplicate to #51 ; we are working on refactoring the solver interfaces and will aim to address this as part of that effort.
