RE: HP questions about program execution speed.
1/2. HOME will be faster always*(have yet to find something equivalent where it is not) for equivalent operations. Less checking of object types, parsing is faster, execution has less overhead, less memory allocations, etc.

3. The largest slowdown from mixing CAS/HOME stuff is that when passing variables to the CAS, or back to HOME, an object converter will convert between home objects/cas objects. This is by necessity much slower due to large amount of work/checking that happens to make things work "pretty much" the way you expect.


So for max performance, avoid doing critical time loops that have any sort of mixing/matching and stay in one side of the other for the duration of a loop to the extent possible.
