If you host your internet sites on a dedicated hosting server, you would expect that they'll perform super fast and that the access speed to them shall depend exclusively on the Internet connection of the visitors. However, this is not going to be the case in the event that the server has bad network connectivity or uses a network card, which simply just cannot deal with high volume of traffic. If this is the case, it shall take a while for your internet sites to load if many people open them simultaneously or visitors might even see error messages. Because of this you could lose customers as almost certainly many people will never revisit your site if they have experienced problems or slow loading speeds. That is why you need to pay attention to the network components of any new server that you get and not only to the main hardware like CPU, RAM or hard disk.
