In the event that you host your internet sites on a dedicated hosting server, you would expect that they'll perform ultra fast and that the access speed to them shall depend only on the Internet connection of the site visitors. Having said that, this is not going to be the case in case the hosting machine has lousy network connectivity or employs a network card, which simply cannot handle high volume of traffic. If this is the case, it'll take quite a long time for your internet sites to load if many people open them simultaneously or visitors could see error messages. Therefore you could lose customers as most likely many people won't return to your website in case they have experienced problems or slow loading speeds. That is why you ought to pay attention to the network components of any new server you buy and not just to the main hardware such as Processor, Ram memory or hard disk drive.
