if i will get that time then that time i can use to load my additional javascript files... so further transaction of user will become speed up....

JavaScript is an event-driven language. You're able to easily create code that responds to certain events.

For what you need, you're probably going to need to use the XMLHttpRequest object (which is the heart of AJAX). XHR has readyState and onreadystatechange properties that can give you information on where data is in the process of being sent/received, or if there's been any requests to begin with.
