When a visitor opens your site, the web browser sends a request to the web server, which in turn executes it and supplies the necessary content as a response. A basic HTML site uses very little system resources because it is static, but database-driven platforms are more demanding and use far more processing time. Every webpage that's served creates 2 forms of load - CPU load, which depends on the time the hosting server spends executing a certain script; and MySQL load, which depends on the number of database queries produced by the script while the customer browses the Internet site. Bigger load will be generated if many people look through a particular website all at once or if a lot of database calls are made simultaneously. 2 illustrations are a discussion board with a huge number of users or an online store in which a visitor enters a term inside a search box and tens of thousands of items are searched. Having thorough statistics about the load which your website generates will enable you to boost the content or see if it is the perfect time to switch to a more powerful kind of hosting service, if the Internet site is simply getting really popular.
