In the event that you host your websites on a dedicated server, you would expect that they will perform super fast and that the access speed to them will depend exclusively on the Internet connection of the website visitors. Nevertheless, this is not going to be the case in case the hosting server has bad network connectivity or employs a network card, which simply just can't handle high volume of traffic. If this is the case, it'll take quite a long time for your internet sites to load if lots of people open them simultaneously or visitors might even see error messages. As a result you could lose visitors as most probably many people won't return to your site if they have experienced problems or slow loading speeds. This is why you need to pay attention to the network components of any new hosting machine which you get and not just to the main hardware like CPU, Ram memory or hard disk drive.
