Multiple parallel ajax calls

Multiple parallel ajax calls

I'm trying to build a page that hhas multiple ajax calls on it. When you do it the old-fashioned way with XmlHttpRequest, you'd create a new xhr object for every call so that they execute simultaneously. If I try to do this in jquery it will only execute a call when the previous one has completed. This makes the page load time completely unacceptable. Does anyone have an idea on how to improve the performance?
