> Many focus solely on memory consumption, which often provides a distorted picture of actual system efficiency.

When other languages can do the same thing with an order of magnitude less RAM, any other efficencies in the system tend to be overshadowed by that and be the sticking point in peoples memories.

You may argue that holding on to this extra memory makes subsequent calls and reads quicker etc, but in my experience generally people are willing to sacrifice milliseconds to gain gigabytes of memory.
