His larger point was having a focus on memory management. He mentioned new and delete in reference to ensuring they match up to avoid memory leaks. He also mentioned smart pointers. If you wanted every drop of CPU performance, you probably wouldn’t be doing lots of memory allocation. You would probably look at every operation in your critical path/loop and ask 1) do I have to do this at all? 2) do I have to do this right here/now? Cut out, defer, pre-allocate until you get as fast as you can.
