In case you host your internet sites on a dedicated hosting server, you would expect that they'll perform extremely fast and that the access speed to them shall depend entirely on the Internet connection of the site visitors. However, this will not be the case in the event that the hosting machine has poor network connectivity or uses a network card, which just can't cope with high volume of traffic. If this is the situation, it'll take a long time for your sites to load if lots of people open them simultaneously or visitors might even see error messages. Therefore you may lose site visitors as probably many people will never revisit your website in the event that they have experienced problems or slow loading speeds. This is why you ought to pay attention to the network components of any new hosting server that you get and not only to the main hardware which includes Central processing unit, RAM or hard disk.
