print is a general solution designed with simplicity in mind. It's about as fast as it can be while still maintaining its level of generality and simplicity of use. If we knew more about your specific needs and issues, we might be able to recommend a solution that is more appropriate for those specifics.

Are you certain that print is your bottleneck? It's possible that it is, as IO is always a "usual suspect", but profiling might alert you to other areas you can focus on where there is more room for improvement.
