Performance Advantages to Iterators?

Question

What (if any) performance advantages are offered by using iterators. It seems like the \'Right Way\' to solve many problems, but does it create faster/more memory-conscious

Answer 1

My inference from many answers above is "Use list to code. If necessary, re-factor using iterators" The difference is not apparent unless you have a large dataset.

Another thing to note is that, even when using lists often, the dataset we are operating upon is progressively smaller and smaller.
