Question about generated proxies

I'm looking at the following example where all of the functions calling web services use a common call back function.

http://www.asp.net/AJAX/Documentation/Live/ViewSample.aspx?sref=Sys.Net.WebServiceGenerics/cs/generics.js

I can see how organization might be a little better using the call back function and a switch statement, but are there performance benefits? Which would have better performance, individual call back functions or the all in one version? Are there any other benefits or detriments between the two?

thanks

There is no performance benifits in using a common callback. You can use the Common Callback when you have to process similar kind of logic for more than one web service call result.
