In the event that you host your sites on a dedicated hosting server, you would expect that they shall perform ultra fast and that the access speed to them shall depend exclusively on the Internet connection of the visitors. Nevertheless, this is not going to be the case in the event that the hosting machine has lousy network connectivity or uses a network card, which just can't deal with high volume of site traffic. If this is the situation, it shall take a long time for your internet sites to load if a lot of people open them at the same time or visitors might even see error messages. Because of this you may lose website visitors as most likely many people won't return to your site in the event that they have experienced difficulties or slow loading speeds. That is why you must pay attention to the network components of any new server you purchase and not only to the main hardware which includes Central processing unit, RAM or hard disk drive.
