Not really. It certainly varies with what you're running, but we typically
measured more like 50% in Smalltalk execution and 50% running C, with the
majority of the C code being non-primitives. So primitives were more like
15-20%. You could say we "targeted" Smalltalk execution to be infinitely
fast ;-), in which case primitives would take a lion's share but it's
probably better not to.
