Put a number on it. "really slow" is not quantitative. What are we specially talking about with respect to the size of the object you are converting? What have you experienced so far? Exactly what is the code you are doing? "simultaneously" would only happen if you parallelized the code and depending on your timings may not be worth it, but it is hard to tell without any useful information.
