A computer-implementable method, system and apparatus. The frequency of reference to an object, also known as 'hotness,' can be collected as a part of a profiling phase during a runtime operation of data-processing system by permitting each reference to the object during the runtime operation to randomly guess a predetermined value associated with the object, such that a correct guess thereof implies that the object is referenced frequently. Thereafter, the frequency of reference to the object can be validated by identifying a particular value in a header associated with the object, in response to collecting the frequency of reference to the object during the profiling phase, thereby increasing the scalability and efficiency of the runtime operation while permitting data associated with the frequency of reference to the object to other applications for immediate use.
