No, no perceptible performance hit, even on IE. There may be one extra function call setting up the request and one extra call handling the response, or depending on how you use your Ajax calls and objects, there may not be any extra calls at all. Either way, you don't have to worry about function calls (even on IE) unless you're dealing with a tight loop doing thousands of them (perhaps hundreds on IE). The reason I may not be ending up with more calls at all is that frequently my ajax callbacks need access to the object initiating the request. Many times people deal with that by calling Function#bind to create the ajax callback so that the calling object becomes `this`. My wrapper supports a `context` parameter (which I've suggested to the Prototype core team[1]) making that unnecessary, so I save the Function#bind call (which involves more function calls and the creation of a function object) on setup and the bound function's call to the actual handler on response -- probably ending up being a bit more efficient.
