In the event that you host your sites on a dedicated hosting machine, you would expect that they will perform ultra fast and that the access speed to them will depend solely on the Internet connection of the site visitors. However, this won't be the case if the server has bad network connectivity or uses a network card, which simply can't deal with high volume of site traffic. If this is the case, it shall take quite a long time for your websites to load if many people open them simultaneously or visitors may see error messages. As a result you may lose visitors as almost certainly many people will never return to your internet site if they have experienced issues or slow loading speeds. That is why you need to pay attention to the network components of any new hosting machine which you acquire and not only to the main hardware like Central processing unit, Ram memory or hard disk.
