Every time a visitor opens your site, the Internet browser sends a request to the web server, which executes it and gives the necessary information as a response. A basic HTML website uses negligible resources for the reason that it's static, but database-driven platforms are more demanding and use a lot more processing time. Every single webpage that's served generates two sorts of load - CPU load, which depends on the span of time the web server spends executing a specific script; and MySQL load, which depends on the amount of database queries produced by the script while the customer browses the Internet site. Higher load shall be generated if a whole lot of people browse a certain site 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 where a visitor enters a term inside a search box and thousands of items are searched. Having in depth data about the load that your website generates will allow you to boost the content or see if it is time for you to switch to a more powerful type of web hosting service, if the Internet site is simply getting very popular.
