In the event that you host your websites on a dedicated hosting machine, you would expect that they'll perform very fast and that the access speed to them will depend entirely on the Internet connection of the site visitors. Having said that, this will not be the case if the server has poor network connectivity or employs a network card, which simply cannot cope with high volume of traffic. If this is the case, it will take a long time for your internet sites to load if a lot of people open them simultaneously or visitors could see error messages. Because of that you may lose customers as almost certainly many people will not revisit your website if they have experienced difficulties or slow loading speeds. That is why you must pay attention to the network components of any new hosting server which you purchase and not just to the main hardware like Central processing unit, Ram memory or hard disk.
