I am beginning to break apart a large JSP file into a some smaller JSP pages so I can reuse this across other areas of the site. 

I can take the approach of leaving as a large Monolithic JSP file that takes params and adjusts it's behavior accordingly. The other approach I can take is breaking it apart so that it's called via jsp:include. 

What is the performance concern in creating additional request calls that are dispatched from within the server? Is it better performance wise to keep it as one jsp page?
