Hi Olivier, The time is basically being spent on checking whether the ma5 interpreter can run properly run here. There is no compilation. This is of course not necessary at this stage. I suggest to implement a way to call the interpreter with all the checks being bypassed that you will then be able to use within aMC. What do yo tihnk?
