In the event that you host your sites on a dedicated hosting machine, you would expect that they'll perform ultra fast and that the access speed to them will depend only on the Internet connection of the visitors. However, this will not be the case in case the hosting server has bad network connectivity or uses a network card, which simply can't cope with high volume of website traffic. If this is the situation, it will take a long time for your sites to load if many people open them at the same time or visitors may see error messages. Therefore you may lose site visitors as in all probability many people will not return to your website in the event that they have experienced difficulties or slow loading speeds. This is the reason why you ought to pay attention to the network components of any new hosting machine which you purchase and not only to the main hardware like Central processing unit, Ram memory or hard drive.
