If you have an HTML Internet site, it likely uses a small amount of system resources due to the fact that it is static, but this isn't the case with dynamic database-driven Internet sites that use PHP scripts and provide much more capabilities. This sort of sites generate load on the hosting server each and every time somebody browses them, as the hosting server needs 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, for example, stores all usernames and posts inside a database, so some load is created any time a thread is opened or an end user searches for a given name. If a lot of people access the forum concurrently, or if every single search involves checking a large number of database entries, this can produce high load and affect the efficiency of the site. In this regard, CPU and MySQL load stats can give you info about the site’s performance, as you can compare the numbers with your traffic data to determine if the website has to be optimized or migrated to another type of hosting platform that will be able to bear the high system load if the site is really popular.
