If you have an HTML Internet site, it likely uses a very small amount of resources simply because it's static, but this is not the case with dynamic database-driven websites that use PHP scripts and provide you with considerably more capabilities. This kind of websites produce load on the website hosting server when somebody browses them, simply because the hosting server requires time to execute the script, to access the database and then to deliver the info requested by the visitor's web browser. A well-known discussion board, as an illustration, stores all usernames and posts in a database, so some load is generated every time a thread is opened or an end user searches for a specific phrase. If a lot of people access the forum at the same time, or if each and every search involves checking tens of thousands of database entries, this may create high load and affect the functionality of the Internet site. In this regard, CPU and MySQL load data can provide you with data about the site’s performance, as you can compare the numbers with your traffic data to decide if the site must be optimized or transferred to a new sort of web hosting platform that'll be able to bear the high system load in the event that the website is popular.
