If you host your sites on a dedicated hosting server, you would expect that they shall perform lightning fast and that the access speed to them will depend exclusively on the Internet connection of the website visitors. However, this won't be the case in the event that the server has lousy network connectivity or employs a network card, which simply just cannot deal with high volume of traffic. If this is the case, it shall take quite a long time for your internet sites to load if a lot of people open them simultaneously or visitors could see error messages. Because of that you could lose customers as most likely many people won't revisit your website in the event that 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 hosting server which you buy and not only to the main hardware such as CPU, RAM or hard disk drive.
