If you host your internet sites on a dedicated server, you would expect that they'll perform very fast and that the access speed to them will depend exclusively on the Internet connection of the site visitors. Having said that, this is not going to be the case if the server has bad network connectivity or relies on a network card, which simply can't handle high volume of traffic. If this is the situation, it will take a long time for your websites to load if many people open them simultaneously or visitors might even see error messages. Thus you may lose site visitors as in all probability many people will never revisit your internet site in case they have experienced issues or slow loading speeds. This is why you need to pay attention to the network components of any new hosting server which you acquire and not only to the main hardware which includes Central processing unit, RAM or hard disk drive.
