In the event that you host your websites on a dedicated hosting server, you would expect that they shall perform extremely fast and that the access speed to them will depend solely on the Internet connection of the site visitors. Having said that, this will not be the case in the event that the hosting machine has lousy network connectivity or relies on a network card, which simply just cannot cope with high volume of site traffic. If this is the situation, it will take a while for your websites to load if many people open them simultaneously or visitors may see error messages. Because of this you might lose website visitors as most likely many people will not revisit your website in the event that they have experienced problems or slow loading speeds. That's why you need to 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, Random access memory or hard disk drive.
