If you host your internet sites on a dedicated hosting machine, you would expect that they will perform very fast and that the access speed to them shall depend exclusively on the Internet connection of the site visitors. However, this is not going to be the case in the event that the hosting server has bad network connectivity or employs a network card, which simply just can't cope with high volume of site traffic. If this is the case, it will take a long time for your websites to load if lots of people open them concurrently or visitors could see error messages. Consequently you may lose website visitors as probably many people will never return to your site if they have experienced issues or slow loading speeds. This is why you must pay attention to the network components of any new hosting machine you get and not just to the main hardware such as Central processing unit, Random access memory or hard drive.
