1. In overlays there is no need for the whole program to reside in main memory .here if say if a program has two functions say f1(50k) and f2(70k) such that they are in mutual exclusion with each other then, the memory of only 70k will be allocated for both the functions and the one that is needed at a particular moment can reside in the main memory . this even saves the memory ,But it is not in case of swapping . here the whole program needs to reside in main memory
2. overlays require careful and time consuming planning while in swapping it is not needed
3. swapping needs to issue system calls for requesting and releasing memory which is not in case of overlays
