In case you host your internet sites on a dedicated hosting server, you would expect that they shall perform super fast and that the access speed to them will depend entirely on the Internet connection of the visitors. However, this won't be the case in case the server has poor network connectivity or relies on a network card, which just cannot deal with high volume of website traffic. If this is the situation, it will take a while for your websites to load if many people open them simultaneously or visitors may see error messages. Consequently you might lose website visitors as probably many people will never return to your internet site in the event that they have experienced difficulties or slow loading speeds. That's why you need to pay attention to the network components of any new hosting machine that you get and not only to the main hardware like Processor, Random access memory or hard disk.
