I'm not sure I understand your point (but I admit I haven't looked very
carefully). As a first reaction, I would not always expect an operation
to take (only) 10 times longer when the size is 10 times bigger. For
example, maybe the latency and speed differences of various CPU caches
and RAM could be a factor.
