1:16:22Q: How do you distinguish between what a lot of people might called "premature optimisation" versus ensuring a good design that allows for high performance? The difference there seems really subtle. I feel that designing for high performance is simply organising the code and writing in such a way that does not unnecessarily slow down the code and prevent future optimisations, while premature optimisation is simply optimising something because you think something will be slow without evidence
