In case you host your websites on a dedicated hosting server, 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. However, this will not be the case in case the hosting server has poor network connectivity or uses a network card, which simply cannot handle high volume of traffic. If this is the situation, it will take a while for your internet sites to load if many people open them concurrently or visitors may see error messages. Because of that you could lose website visitors as almost certainly many people won't revisit your website if 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 that you buy and not only to the main hardware which includes Processor, Random access memory or hard disk drive.
