What's the difference between efficiency and performance?

Efficiency


Definition:

  • (n.) The quality of being efficient or producing an effect or effects; efficient power; effectual agency.
  • (n.) The ratio of useful work to energy expended.

Performance


Definition:

  • (n.) The act of performing; the carrying into execution or action; execution; achievement; accomplishment; representation by action; as, the performance of an undertaking of a duty.
  • (n.) That which is performed or accomplished; a thing done or carried through; an achievement; a deed; an act; a feat; esp., an action of an elaborate or public character.
