The new software includes an enhancer that boosts performance.
Enhancer → It is formed from "enhance" (from Old French *enhanter*, meaning to raise or elevate) and "-er" (meaning a person or thing that performs an action). The word "enhancer" refers to a person or thing that raises or improves something.
Think of someone or something that 'raises' or 'improves' — that's what an enhancer does.
