Do we think there is still room for getting the iterator version to have less overhead (in these simple cases), or have the majority of optimisations already been done?

these questions are hard because there's different tiers and they don't necessarily kick in at the same times and conditions. it will probably always be the case that the initial tier is going to be slower. I don't know if the above tests were done in a way which allowed the higher tiers to kick in, and also of course you don't necessarily always care about the higher tiers

they were done with the goal of reaching higher tiers, and the browser-oriented implementations did bump twice
