In the event that you host your websites on a dedicated server, you would expect that they shall perform lightning fast and that the access speed to them shall depend entirely on the Internet connection of the website visitors. Nevertheless, this is not going to be the case if the hosting server has poor network connectivity or employs a network card, which simply cannot deal with high volume of traffic. If this is the situation, it will take quite a long time for your sites to load if a lot of people open them simultaneously or visitors might even see error messages. Because of this you might lose visitors as most likely many people will not return to your site in case they have experienced issues or slow loading speeds. This is the reason why you must pay attention to the network components of any new server that you purchase and not only to the main hardware such as Central processing unit, RAM or hard disk.
