If you host your websites on a dedicated server, you would expect that they will perform lightning fast and that the access speed to them shall depend entirely on the Internet connection of the site visitors. Having said that, this won't be the case if the hosting machine has bad network connectivity or employs a network card, which just can't cope with high volume of traffic. If this is the case, it'll take a long time for your internet sites to load if lots of people open them concurrently or visitors might even see error messages. Consequently you may lose customers as in all probability many people won't revisit your internet site if they have experienced difficulties or slow loading speeds. That is why you should pay attention to the network components of any new server you buy and not just to the main hardware which includes Central processing unit, Random access memory or hard disk.
