How to Measure Execution Time of a Program

Measuring the performance of a program means keeping track of the consumption of resources used by the program.In addition to simple technical performance, such as looking closely at RAM and CPU, it is useful to monitor the execution time of a certain task. Tasks such as increasing sorting of a set of values can take a long time depending on the algorithm used.Before delving into optimizing an algorithm, it is useful to understand how to measure the execution time of a program.
