>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.

Vfp class (in the future, it could be COM Object) , VFP7 SP1, Windows 2000 or XP...

Physical, and Virtual memory, clock speed and I/O parameters depends client hard and it will be different in cliente.

>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.

I need know tools for know that, external tools, API or VFP function for make the case study for this and another objects, for memory use principally.
