As just noted, the amount of code that must be executed serially limits how much of a speedup you can expect from parallel execution. This idea has been formalized by what is known as Amdahl's Law, named after Gene Amdahl, who first stated the law in the late sixties. In a nutshell, Amdahl's Law states that the serial ...

Amdahl's law applies only to the cases where the problem size is fixed. In practice, as more computing resources become available, they tend to get used on larger problems (larger datasets), and the time spent in the parallelizable part often grows much faster than the inherently serial work.

Web10) Amdahl’s Law is as applicable to software as it is to hardware. An oft-cited programming truism states that a program spends 90% of its time executing 10% of its code. Thus, tuning a small amount of program code can often have an enormous effect on the overall performance of a software product.
