If you host your internet sites on a dedicated hosting machine, you would expect that they will perform lightning fast and that the access speed to them will depend solely on the Internet connection of the visitors. However, this is not going to be the case in case the hosting machine has bad network connectivity or employs a network card, which simply just cannot handle high volume of traffic. If this is the case, it will take a very long time for your sites to load if a lot of people open them simultaneously or visitors could see error messages. Therefore you may lose visitors as almost certainly many people won't revisit your internet site if they have experienced problems or slow loading speeds. This is the reason why you should pay attention to the network components of any new hosting machine which you purchase and not just to the main hardware which includes CPU, Ram memory or hard drive.
