In the event that you host your internet sites on a dedicated hosting machine, you would expect that they'll perform ultra fast and that the access speed to them will depend solely on the Internet connection of the site visitors. However, this will not be the case in case the server has lousy network connectivity or uses a network card, which simply just cannot handle high volume of website traffic. If this is the situation, it will take a long time for your sites to load if a lot of people open them concurrently or visitors may see error messages. Because of this you might lose customers as almost certainly many people will not revisit your site if they have experienced problems or slow loading speeds. This is the reason why you ought to pay attention to the network components of any new server that you get and not only to the main hardware such as CPU, RAM or hard disk drive.
