Performance test for JavaScript

Question

I've developed a framework for web applications that heavily depends on JavaScript and JQuery and i'm facing big performance issue in the client processing specially when handling some UI changes... and because i am using many JavaScript libraries i will not be able to pass on every JavaScript function,callback and event handler to check each performance.

Is there any way to detect the specific functions that causes long time processing to be able to optimize them or even replace them?

使用Chrome开发人员工具或Firebug中的配置文件功能，可以大致了解所调用的每个功能，堆栈和运行时间。
