In a way, this is a question about Amdahl’s law that relates the speedup to the improvement of the individual components of a task. The corollary of Amdahl’s law is, “Make the common case fast”. It’s also rather similar to the common saying, “A chain is as strong as its weakest link”. Consequently, if you are speeding up a system, it is necessary to determine how much each improvement would cost, and how much each improvement would contribute to speeding up the system.
