Good point, Does this mean that since I am invoking the GC to avoid crashing and since the FFI arrays are outside of it's purview that it may be able to complete the GC operation faster? My average GC's run about 0.3 seconds so a saving there would be helpful.

Especially with out-of-cache loads, that's a considerable cost you need to factor into the whole comparison. --Mike
