If you host your websites on a dedicated hosting server, you would expect that they'll perform lightning fast and that the access speed to them will depend solely on the Internet connection of the visitors. Having said that, this won't be the case in the event that the hosting machine has bad network connectivity or uses a network card, which simply just cannot cope with high volume of traffic. If this is the situation, it will take a long time for your websites to load if many people open them simultaneously or visitors might even see error messages. Because of this you may lose website visitors as most likely many people will not return to your site if they have experienced difficulties or slow loading speeds. This is the reason why you need to pay attention to the network components of any new server that you acquire and not just to the main hardware such as Processor, RAM or hard disk.
