Amdahls law

Amdahl's Law is a guideline for improving the performance of computer systems. The basic idea is that a computer system will work much faster if you speed up the most frequently used program cycle. The improvement in overall performance depends on the improvement in individual performance and frequency of use.

Amdahl's law relates the various factors influencing the overall performance of a computer system. For this the new execution time is determined considering the old execution time, the unused and used computing power as well as the acceleration in the execution.
