The CPU load depends upon the length of time a server spends executing a script every time a visitor opens a page on a specific script-driven site. Static HTML sites use barely any CPU time, but it is not so with the considerably more advanced and functional scripts, that use a database and display dynamic content. The more individuals open this sort of a website, the more load shall be generated on the web server and if the database is big, the MySQL server will be loaded too. An illustration of what can cause high load is an online store with a huge number of products. If it is popular, many people shall be browsing it simultaneously and if they seek out items, the entire database containing all the products will also be frequently accessed by the script, resulting in high load. In this light, having CPU and MySQL load data can provide an idea of how the website is doing, if it needs to be optimized or if you simply just need a more effective website hosting solution - if the Internet site is popular and the established setup can't handle the load.
