If you have an HTML Internet site, most likely it uses a small amount of resources simply because it's static, but this is not so with dynamic database-driven sites that use PHP scripts and provide considerably more features. This sort of Internet sites create load on the website hosting server each and every time anyone browses them, as the hosting server requires time to execute the script, to access the database and then to deliver the information requested by the visitor's Internet browser. A well known discussion board, as an illustration, stores all usernames and posts within a database, so some load is created every single time a thread is opened or an end user looks for a particular name. If lots of people access the forum all at once, or if every single search involves checking tens of thousands of database entries, this can generate high load and affect the efficiency of the site. In this regard, CPU and MySQL load statistics can provide information about the site’s performance, as you can compare the numbers with your traffic stats to determine if the site must be optimized or moved to a different type of web hosting platform which will be able to bear the high system load in case the Internet site is extremely popular.
