A very complicated issue since caches and other brilliant inventions enter
the picture. Burst-filling a block of memory is likely to be the most
optimized operation in the memory subsystem; for instance, some RAM designs
have a 'memset' that works in parallel with the CPU.
Let's just say that I've never seen a memset() in a profiler report. Perhaps
it's just me.
