User controls and custom controls are two types of Web controls. User controls are easy to create as handling it is same as that of a standard Web Form. Custom controls are compiled and distributed in binary format.

But with regard with performance I think both acts the same manner over another. Am I right? If so what is the reason for the same.

Yes you are right that with regard with performance both acts the same manner over another. This is because neither has a distinct advantage over the other. Both derive from System.Web.UI.Control and both are compiled into assemblies. Hence, performance is not a factor to consider when choosing between user and custom controls.
