When a visitor opens your website, the Internet browser sends a request to the server, which in turn executes it and provides the necessary data as a response. A standard HTML website uses negligible system resources due to the fact that it is static, but database-driven platforms are more requiring and use more processing time. Every webpage which is served creates two types of load - CPU load, that depends on the length of time the web server spends executing a particular script; and MySQL load, that depends on the amount of database queries created by the script while the customer browses the site. Bigger load shall be generated if a lot of people look through a particular Internet site concurrently or if a lot of database calls are made at the same time. Two good examples are a discussion board with many users or an online store where a client enters a term in a search box and a large number of items are searched. Having detailed data about the load which your Internet site generates will help you optimize the content or see if it is the perfect time to switch to a more powerful sort of website hosting service, if the site is simply getting really popular.
