In the event that you host your internet sites on a dedicated server, you would expect that they'll perform lightning fast and that the access speed to them will depend exclusively on the Internet connection of the website visitors. Nevertheless, this won't be the case if the hosting machine has poor network connectivity or employs a network card, which just can't handle high volume of website traffic. If this is the situation, it shall take a very long time for your websites to load if lots of people open them concurrently or visitors may see error messages. Thus you might lose website visitors as almost certainly many people won't revisit your website if they have experienced issues or slow loading speeds. That's why you ought to pay attention to the network components of any new server that you get and not just to the main hardware such as CPU, Random access memory or hard disk.
