speedup

Faster than before

A speedup is an increase in speed or rate, especially in industrial or computational contexts.

In manufacturing, speedup often refers to management requiring workers to produce more without additional compensation: The new speedup had assembly line workers exhausted by lunch.

In computing, speedup measures how much faster a parallel algorithm runs compared to its sequential version.
