Amdahl's law (or Amdahl's argument) is a formula that gives the theoretical speedup in latency of the execution of a task at a fixed workload that can be expected of a system whose resources are improved. Specifically, it states that "the overall performance improvement gained by optimizing a single part of a system is limited by the fraction of time that the improved part is actually used".
