Admittedly, modern memory managers became very good at satisfying these conflicting requirements, so has any change been made to beat them at their game? I'd say, probably not. But there are alternative general memory managers that are touting their performance advantages over the standard malloc function. Should we use them instead?

However, as one study has shown, they are all on a par, and more importantly, each of them can outperform the other ones under certain conditions. So, changing the memory manager isn't a silver ...
