If you have an HTML Internet site, it likely uses a small amount of resources due to the fact that it is static, but this isn't so with dynamic database-driven websites that use PHP scripts and provide much more features. This sort of sites generate load on the hosting server anytime someone browses them, simply because the server needs time to execute the script, to access the database and then to deliver the information requested by the visitor's web browser. A popular discussion board, for instance, stores all usernames and posts in a database, so some load is generated any time a thread is opened or an end user looks for a certain term. If many people access the forum at the same time, or if each search involves checking a large number of database entries, this can generate high load and affect the efficiency of the website. 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 decide if the website must be optimized or moved to another kind of hosting platform which will be able to bear the high system load if the Internet site is extremely popular.
