Each time a visitor opens your Internet site, the browser sends a request to the hosting server, which in turn executes it and provides the desired content as a response. A basic HTML website uses minimal resources for the reason that it is static, but database-driven platforms are more demanding and use a lot more processing time. Every single webpage which is served produces 2 kinds of load - CPU load, which depends on the time period the hosting server spends executing a certain script; and MySQL load, that depends on the amount of database queries produced by the script while the end user browses the Internet site. Bigger load will be produced if a lot of people browse a certain Internet site simultaneously or if a lot of database calls are made all at once. 2 examples are a discussion board with tens of thousands of users or an online store in which a client enters a term inside a search box and thousands of items are searched. Having detailed stats about the load your Internet site generates will enable you to boost 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.
