In case you host your internet sites on a dedicated server, you would expect that they will perform extremely fast and that the access speed to them will depend entirely on the Internet connection of the website 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 cope with high volume of website traffic. If this is the case, it shall take a while for your websites to load if a lot of people open them concurrently or visitors may see error messages. As a result you might lose customers as almost certainly many people will not return to your website if they have experienced problems or slow loading speeds. That is why you ought to pay attention to the network components of any new hosting server you buy and not just to the main hardware like CPU, Ram memory or hard disk.
