If you host your internet sites on a dedicated hosting machine, you would expect that they'll perform very fast and that the access speed to them will depend entirely on the Internet connection of the website visitors. Having said that, this will not be the case in the event that the hosting server has bad network connectivity or relies on a network card, which just can't cope with high volume of traffic. If this is the case, it shall take a while for your sites to load if lots of people open them simultaneously or visitors might even see error messages. Consequently you may lose website visitors as probably many people will not revisit your internet site in the event that they have experienced problems or slow loading speeds. That is why you should pay attention to the network components of any new hosting server you get and not only to the main hardware like Central processing unit, Random access memory or hard disk.
