Probably not much but performance is a funny thing. 
Only the profiler will really tell you.

There is pretty good guidance in the documentation. Its 
really pretty straighforward.
Try it, if you get stuck ask. Its probably the easiest way.

If you have Programming Python it has a chapter on using 
the profiler too.
