Amdahl's Law, also known as Amdahl's argument, is used to find the maximum expected improvement to an overall process when only a part of the process is improved. It is often applied in the field of parallel-computing to predict the theoretical maximum speedup achievable by using multiple processors.

Marty, “Amdahl's law in the multicore era,” Before a buffering effect works, a time delay exists. Amdahl and Eberg studied the effect of dynamics on platform responses in terms of energy dissipation and the United States and Europe, with Japan lagging behind.

We also help to draw right conclusions in the context of your own performance tuning task at hand.

Amdahl's law, named after a computer architect named Gene Amdahl and his work in the 1960s, is a law showing how much latency can be taken out of a performance task by introducing parallel computing. In parallel computing, Amdahl's law is mainly used to predict the theoretical maximum speedup for program processing using multiple processors. Amdahl's law is a model for the relationship between the expected speedup of parallelized implementations of an algorithm relative to the serial algorithm, under the assumption that the problem size remains the same when parallelized." In computer architecture, Amdahl’s law (or Amdahl’s argument) is a formula which gives the theoretical speedup in latency of the execution of a task at fixed workload that can be expected of a system whose resources are improved.
The Amdahl's law predict that for every given parallel portion (e.g. 75%) of a program you can speed up execution only so far (e.g. at most 4 times) even if you use

Amdahls lag säger att det är den långsammaste komponenten som bestämmer ett systems prestationsförmåga. Gene Amdahls namn är förknippat med superdatorer - flaskhalsar kallar vi sådana långsamma enheter.
