In case you host your internet sites on a dedicated server, you would expect that they'll perform very fast and that the access speed to them will depend exclusively on the Internet connection of the visitors. Having said that, this is not going to be the case if the server has bad network connectivity or relies on a network card, which simply just can't cope with high volume of website traffic. If this is the situation, it will take a while for your internet sites to load if lots of people open them at the same time or visitors could see error messages. Because of that you may lose website visitors as almost certainly many people won't return to your website if they have experienced problems or slow loading speeds. This is the reason why you should pay attention to the network components of any new hosting machine which you purchase and not only to the main hardware such as CPU, Random access memory or hard disk drive.
