In the event that you host your internet sites on a dedicated hosting server, you would expect that they shall perform extremely 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 case the hosting machine has poor network connectivity or uses a network card, which just cannot handle high volume of site traffic. If this is the situation, it will take a while for your internet sites to load if many people open them simultaneously or visitors may see error messages. Consequently you may lose website visitors as probably many people will never return to your site in the event that they have experienced issues or slow loading speeds. This is the reason why you ought to pay attention to the network components of any new server which you purchase and not only to the main hardware such as Central processing unit, RAM or hard disk.
