Regardless of whether a web page hosting is by nature dynamic or static, the CPU of the web server that provides for these services is whats being used to transfer information to your website for your traffic to read. The dynamic type of hosting affects the performance of your site because it takes up ore CPU cycles.

The typical scenario that leads to the server bugging down is when one website engages in a lot of activity that it takes up a lot of the CPUs resources at once. The scripts will have to put up the template and do other things to present the entire site to the visitor. If you dont happen to be the one taking advantage of this, your web page hosting is obviously on the losing end of the stick.

Remedies to this problem vary a bit, but there are times when the web hosting site will simply ask you to upgrade to a better hosting package for more convenience. Or you can opt for a dedicated server, where the CPU usage is used exclusively for your web page hosting.
