Most of the Artificial Intelligent CMS scripts are FREE (open source). But to use them one needs a piece of virtual property to install it on & a road for public traffic, and that’s where the cost start to incur. How big is the CMS script with all the text, images, css and java, and how much of that information is being transmitted to the public at any
given moment, is referred to as bandwidth.
One will always want a Page that is loadable in a few seconds. No one will wait 5 minutes just to load a car image. 56k a second is a good benchmark. This means don’t use a 5 megapixel picture straight from a phone on a site. instead
make a smaller version of it, place it on the page and hyperlink the 5k thumbnail image to the 5 megapixel picture, thus allowing anyone the ability to see the large image if they choose so. 1000k = 1 megapixel.
There are also plenty of web site speed tests that will analyze a Website Load Time http://www.websiteoptimization.com/services/analyze/. On average it should not take more than 2-3 seconds to load one of the pages into an internet browser such as Google chrome, Firefox or internet explorer.
