Each time a visitor opens your Internet site, the Internet browser sends a request to the web server, which executes it and provides the required data as a response. A standard HTML website uses negligible resources for the reason that it's static, but database-driven platforms are more requiring and use a lot more processing time. Each page which is served generates 2 kinds of load - CPU load, that depends on the time period the hosting server spends executing a particular script; and MySQL load, that depends on the number of database queries created by the script while the user browses the Internet site. Bigger load will be produced if a lot of people look through a particular website at the same time or if loads of database calls are made simultaneously. Two illustrations are a discussion board with tens of thousands of users or an online store where a client enters a term inside a search box and thousands of items are searched. Having comprehensive data about the load your Internet site generates can help you improve the content or see if it is time for you to switch to a more powerful sort of web hosting service, if the Internet site is simply getting quite popular.
