Sure if your entire program is only one loop that iterates over 100 things that fit in an L1 cache. If you write an entire program with this thinking, a significant program, each of those "negligible performance hits" will usually add up to a poorly performing program. Back in the day people called "optimising" the application of clever algorithms and tricks to squeeze more out of a computer, today we call it ripping all the shitty slow code out of programs because devs couldn't be arsed to write things properly because "computers are fast". </ yes it's a rant, it's why lots of stuff sucks, make nice things pleeease
