I agree completely. Frontend optimizations can probably give a lot more in the short term than these kinds of backend optimizations. Unfortunately, even if it's paying down technical debt, if you're trying to squeeze out more cycles with your low-level code, a lot of the time it's issues on the algorithm level. When refactoring there, these kinds of optimizations should always be at the back of your head, even if it's just to explain why moving the for loop up 5 lines gave the function a 2% performance boost.
