This sounds like a major kludge to me. What if the page keeps firing events? What if the page is relying on cues from the browser (dimensions, cookies, JS capabilities, etc.) to know the correct requests to make. If you care about performance you should design an architecture where it's possible to determine exactly which parts should and can be executed on the server.
