If you have an HTML site, it likely uses a very small amount of resources simply because it is static, but this is not the situation with dynamic database-driven Internet sites that use PHP scripts and offer you much more functions. This sort of Internet sites generate load on the web hosting server each and every time anyone browses them, simply because the server needs time to execute the script, to access the database and then to deliver the data requested by the visitor's Internet browser. A famous discussion board, for example, stores all usernames and posts within a database, so some load is generated every time a thread is opened or a user searches for a certain word. If many people connect to the forum at the same time, or if each and every search involves checking a large number of database entries, this could produce high load and affect the efficiency of the website. In this regard, CPU and MySQL load statistics can present you with information about the site’s functionality, as you can compare the numbers with your traffic statistics and see if the Internet site should be optimized or migrated to a new type of website hosting platform that'll be able to bear the high system load if the Internet site is very popular.
