Performance Tuning is great work to do because there is a constant wave of immediate feedback and the metrics for success are easy to quantify.
Did it go faster? Win.
Did it reduce costs? Win.
Did it use less resources? Win.
At some point, those returns become smaller, you go from optimizing hours/minutes to seconds/milliseconds.
It’s at that point you have to ask whether the effort you’re putting is going to get you the returns to justify the time you are expending into the work.
At some point, you have to ask if Optimizing the Optimized is worth it.
Sometimes, things just run.
