Without further qualification, the answer is unknowable - it depends on whether the object is instanced internally as a VFP class or a COM Object, the available physical and Virtual memory on the PC, the clock speed of the system, any number of I/O parameters for the system, and obviously the version of VFP and Windows in use.

The pragmatic approach is to write a small test harness to instance these complex objects and do a synthetic benchmark of the performance issues you need to test. IOW, write a simple case study that creates multiple object instances and exercises the system to test the performance issues of interest - disk, video, user response, etc.
