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