If you have an HTML Internet site, most likely it uses a very small amount of resources because it is static, but this isn't so with dynamic database-driven Internet sites that use PHP scripts and provide you with way more functions. This kind of Internet sites create load on the website hosting server when somebody browses them, simply because the web server requires time to execute the script, to access the database and then to supply the data requested by the visitor's web browser. A well-known discussion board, as an illustration, stores all usernames and posts inside a database, so some load is generated each time a thread is opened or an end user looks for a certain name. If a lot of people connect to the forum concurrently, or if each and every search involves checking hundreds of thousands of database entries, this could generate high load and affect the performance of the Internet site. In this regard, CPU and MySQL load statistics can provide you with data about the site’s efficiency, as you can compare the numbers with your traffic stats to make a decision if the website should be optimized or transferred to another type of website hosting platform which will be able to bear the high system load in the event that the site is extremely popular.
