Every time a visitor opens your Internet site, the web browser sends a request to the web server, which executes it and provides the desired information as a response. A standard HTML website uses very little resources for the reason that it's static, but database-driven platforms are more requiring and use far more processing time. Every page that is served creates 2 kinds of load - CPU load, which depends on the length of time the web server spends executing a particular script; and MySQL load, which depends on the total number of database queries created by the script while the user browses the website. Bigger load shall be produced if many people surf a particular Internet site simultaneously or if a lot of database calls are made all at once. 2 illustrations are a discussion board with a huge number of users or an online store where a visitor enters a term within a search box and a large number of items are searched.
