In case you host your internet sites on a dedicated hosting server, you would expect that they will perform super fast and that the access speed to them shall depend only on the Internet connection of the website visitors. However, this will not be the case in case the hosting machine has lousy network connectivity or relies on a network card, which simply cannot cope with high volume of website traffic. If this is the situation, it'll take quite a long time for your internet sites to load if a lot of people open them at the same time or visitors may see error messages. As a result you may lose visitors as most probably many people will never return to your internet site in the event that they have experienced problems or slow loading speeds. This is the reason why you ought to pay attention to the network components of any new server which you purchase and not just to the main hardware such as Central processing unit, Ram memory or hard disk drive.
