In the event that you host your internet sites on a dedicated hosting machine, you would expect that they will perform extremely fast and that the access speed to them shall depend solely on the Internet connection of the visitors. Nevertheless, this is not going to be the case if the hosting server has lousy network connectivity or uses a network card, which just cannot deal with high volume of website traffic. If this is the situation, it shall take a while for your websites to load if many people open them concurrently or visitors might even see error messages. Consequently you could lose visitors as probably many people won't return to your website if they have experienced difficulties or slow loading speeds. This is why you need to pay attention to the network components of any new hosting machine that you acquire and not only to the main hardware such as Central processing unit, RAM or hard disk.
