In case you host your internet sites on a dedicated hosting machine, you would expect that they will perform super fast and that the access speed to them will depend solely on the Internet connection of the visitors. Nevertheless, this is not going to be the case in case the server has lousy network connectivity or employs a network card, which simply can't deal with high volume of website traffic. If this is the situation, it will take a very long time for your sites to load if lots of people open them at the same time or visitors could see error messages. Therefore you could lose customers as almost certainly many people will not return to your internet site in case they have experienced difficulties or slow loading speeds. This is the reason why you should pay attention to the network components of any new hosting server which you buy and not just to the main hardware like Processor, Ram memory or hard disk drive.
