In case you host your internet sites on a dedicated hosting machine, you would expect that they'll perform ultra fast and that the access speed to them shall depend exclusively on the Internet connection of the website visitors. Having said that, this won't be the case if the hosting server has bad network connectivity or uses a network card, which simply cannot deal with high volume of traffic. If this is the case, it shall take quite a long time for your internet sites to load if a lot of people open them at the same time or visitors might even see error messages. Because of that you may lose visitors as probably many people will not revisit your internet site in case they have experienced problems or slow loading speeds. That's why you must pay attention to the network components of any new hosting machine which you purchase and not only to the main hardware which includes CPU, RAM or hard disk drive.
