If you have an HTML website, it probably uses a very small amount of system resources simply because it is static, but this isn't so with dynamic database-driven websites that use PHP scripts and provide you with far more functions. This sort of Internet sites produce load on the website hosting server every time anyone browses them, as the web server needs time to execute the script, to access the database and then to provide the content requested by the visitor's Internet browser. A famous 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 certain term. If lots of people access the forum all at once, or if each search involves checking tens of thousands of database entries, this can produce high load and affect the overall performance of the Internet site. In this regard, CPU and MySQL load statistics can present you with information about the site’s efficiency, as you can compare the numbers with your traffic statistics and see if the site should be optimized or moved to a new sort of website hosting platform that will be able to bear the high system load in case the site is very popular.
