The objective of the theoretical part is aimed at events occurring during painting of the website, introduction of the metrics itself, their value, reasons to monitor them and the monitoring methods and tools. In the practical part, tests of popular websites are made to illustrate the most common reasons for slow loading websites. Based on this research I will make a sample website with ideal settings of monitored parameters. A part of the practical section is an analysis of to professional public about using optimization techniques in the form of online quizzes. |
