Each time a visitor opens your Internet site, the browser sends a request to the web server, which in turn executes it and provides the required data as a response. A standard HTML site uses minimal system resources due to the fact that it's static, but database-driven platforms are more demanding and use more processing time. Every single page that's served produces two types of load - CPU load, that depends on the time the hosting server spends executing a specific script; and MySQL load, which depends on the total number of database queries produced by the script while the customer browses the Internet site. Bigger load will be generated if a whole lot of people look through a certain Internet site concurrently or if many database calls are made all at once. 2 illustrations are a discussion board with thousands of users or an online store where a client enters a term inside a search box and thousands of items are searched. Having detailed data about the load that your website generates will enable you to boost the content or see if it is the perfect time to switch to a more powerful type of hosting service, if the Internet site is simply getting extremely popular.
