- (Wikipedia, 2015) ⇒ In computer architecture, speedup is a metric for improvement in performance between two systems processing the same problem. More technically, is it the improvement in speed of execution of a task executed on two similar architectures with different resources. The notion of speedup was established by Amdahl's law, which was particularly focused on parallel processing. However, speedup can be used more generally to show the effect on performance after any resource enhancement.
