I just tried again the performances of GLPK against COIN-OR with a new option I had not noticed before, and the difference is now only of 2 : 1 It is a bit better than the 30 : 1 found with the previous example and perhaps it will let me code the algorithms I needed without waiting for COIN-OR to get implemented ( which could take some time after all considering your answers... ;-) )
