Not create a object everytime

Hi, well i'm testing ladon and i like it, but i have a question.
I have a complex object that make a lot of fuctions and a take a lot of time to create it.
I want that my service call a fuction of that object, but it create the object in every single request.

I try to create in the import module and out of service class.

Is possible to create a object and leave waiting until requests come? if yes, how?

Ty a lot!
