$s p e e d u p = \frac{P e r f o r m a n c e o f e n t i r e t a s k u s i n g t h e e n h a n c e m e n t w h e n p o s s i b l e}{P e r f o r m a n c e f o r e n t i r e t a s k w i t h o u t u s i n g t h e e n h a n c e m e n t}$

Using the definition of performance, we can write it as...

$s p e e d u p = \frac{E x e c u t i o n t i m e f o r e n t i r e t a s k w i t h o u t u s i n g t h e e n h a n c e m e n t}{E x e c u t i o n t i m e f o r e n t i r e u s i n g t h e e n h a n c e m e n t w h e n p o s s i b l e}$
