Sometimes a speedup of more than A when using A processors is observed in parallel computing, which is called super-linear speedup. In marketing contexts, speedup curves are more often used, largely because they go up and to the right and thus appear better to the less-informed. there is no need to plot a "perfect speedup" curve.it is easy to see how well the improvement of the system is working.
all of the area in the graph is useful (whereas in speedup curves half of the space is wasted).In engineering contexts, efficiency curves are more often used for graphs than speedup curves, since Programs with linear speedup and programs running on a single processor have an efficiency of 1, while many difficult-to-parallelize programs have efficiency such as 1/ln( s) that approaches 0 as the number of processors A = s increases. Latency of an architecture is the reciprocal of the execution speed of a task: Speedup can be defined for two different types of quantities: latency and throughput. However, speedup can be used more generally to show the effect on performance after any resource enhancement. The notion of speedup was established by Amdahl's law, which was particularly focused on parallel processing. More technically, it is the improvement in speed of execution of a task executed on two similar architectures with different resources. In computer architecture, speedup is a number that measures the relative performance of two systems processing the same problem. Look up speedup in Wiktionary, the free dictionary.
