Every time a visitor opens your Internet site, the Internet browser sends a request to the web server, which in turn executes it and supplies the desired content as a response. A basic HTML website uses negligible system resources due to the fact that it is static, but database-driven platforms are more demanding and use far more processing time. Each and every page which is served creates 2 kinds of load - CPU load, which depends on the amount of time the server spends executing a specific script; and MySQL load, that depends on the total number of database queries generated by the script while the client browses the website. Higher load shall be generated if loads of people browse a certain website simultaneously or if a lot of database calls are made simultaneously. 2 examples are a discussion board with a large number of users or an online store in which a customer enters a term within a search box and tens of thousands of items are searched. Having detailed stats about the load that your site generates can help you boost the content or see if it is time for you to switch to a more powerful kind of web hosting service, if the Internet site is simply getting really popular.
