If you have an HTML website, in all probability it uses a very small amount of resources due to the fact that it is static, but this is not the situation with dynamic database-driven websites that use PHP scripts and provide far more functions. This kind of Internet sites create load on the web hosting server every time anyone browses them, due to the fact that 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 famous discussion board, as an illustration, stores all usernames and posts in a database, so some load is produced each time a thread is opened or a user looks for a specific phrase. If a lot of people access the forum concurrently, or if each and every search involves checking tens of thousands of database entries, this may generate high load and affect the functionality of the Internet site. In this regard, CPU and MySQL load stats can present you with info about the site’s overall performance, as you can compare the numbers with your traffic stats to decide if the site needs to be optimized or migrated to a new sort of website hosting platform which will be able to bear the high system load in the event that the website is very popular.
