If you have an HTML website, it probably uses a very small amount of resources due to the fact that it's static, but that isn't so with dynamic database-driven Internet sites that use PHP scripts and provide a lot more functions. This sort of websites produce load on the hosting server every time anyone browses them, due to the fact that the server needs time to execute the script, to access the database and then to supply the info requested by the visitor's Internet browser. A well known discussion board, for example, stores all usernames and posts within a database, so some load is created every time a thread is opened or an end user searches for a specific phrase. If a lot of people access the forum all at once, or if every search involves checking a large number of database entries, this may create high load and affect the performance of the website. In this regard, CPU and MySQL load statistics can provide info about the site’s overall performance, as you can compare the numbers with your traffic statistics and see if the Internet site must be optimized or transferred to a new kind of hosting platform that will be able to bear the high system load if the site is extremely popular.
