How fast a website is going to open depends not just on the Internet connection of the website visitor, but also on the connection of the server in which the site is hosted and on the network infrastructure - routers, server network card, etcetera. Slow connection or hardware which can't handle a high volume of inbound and outbound traffic might have strong influence on the consumer experience of your site visitors and the efficiency of your internet site because people will most probably see error messages that the website is not available or it shall take a very long time for your content to load. In the event that such a thing occurs, it is not likely that the site visitors shall revisit the site. That is why you should always examine the connectivity of any hosting machine that you buy and not just the main hardware components like hard disk drive, cpu and physical memory.
