In case you host your websites on a dedicated hosting server, you would expect that they'll perform lightning fast and that the access speed to them shall depend only on the Internet connection of the visitors. Nevertheless, this is not going to be the case in case the server has bad network connectivity or relies on a network card, which simply just can't deal with high volume of traffic. If this is the situation, it will take a long time for your internet sites to load if many people open them at the same time or visitors could see error messages. Because of this you may lose customers as most probably many people will not return to your website in case they have experienced difficulties or slow loading speeds. That's why you should pay attention to the network components of any new hosting server that you acquire and not only to the main hardware which includes CPU, Ram memory or hard disk drive.
