To crystal storm. The definition of efficacy is to determine how effective something is. Synonyms for it are effectivness and potency, both whom are synonomous with quality. Efficiency is not the same as efficacy and quality. Efficiency is how quick you get a task done. Ex make 20 pancakes but they are lacking in taste or are falling apart (lacking in quality or efficacy.)

One of the limitations on the efficacy page is that one can achieve a desired effect but without efficiency they may not get it as soon as they would like.

Efficiency is normally tied to quanity just as efficacy is tied to quality. That debate on which is better quality vs quantity is the same for efficiency vs efficacy
