If you host your sites on a dedicated hosting machine, you would expect that they shall perform ultra fast and that the access speed to them will depend only on the Internet connection of the site visitors. Nevertheless, this will not be the case in case the server has poor network connectivity or relies on a network card, which simply cannot handle high volume of site traffic. If this is the situation, it will take a long time for your internet sites to load if many people open them concurrently or visitors might even see error messages. Therefore you may lose site visitors as most likely many people will never revisit your website if they have experienced problems or slow loading speeds. That is why you ought to pay attention to the network components of any new server that you acquire and not only to the main hardware such as Central processing unit, Ram memory or hard drive.
