In the event that you host your internet sites on a dedicated hosting server, you would expect that they shall perform ultra fast and that the access speed to them shall depend entirely on the Internet connection of the website visitors. However, this won't be the case in the event that the server has bad network connectivity or relies on a network card, which simply just cannot cope with high volume of website traffic. If this is the situation, it will take a while for your sites to load if lots of people open them concurrently or visitors could see error messages. Because of this you might lose visitors as most likely many people won't revisit your site if they have experienced difficulties or slow loading speeds. This is the reason why you should pay attention to the network components of any new hosting server that you buy and not only to the main hardware such as Central processing unit, RAM or hard disk drive.
