In the event that you host your internet sites on a dedicated hosting server, you would expect that they will perform super fast and that the access speed to them shall depend only on the Internet connection of the website visitors. Having said that, this will not be the case if the server has bad network connectivity or uses a network card, which just can't handle high volume of website traffic. If this is the case, it'll take a while for your sites to load if lots of people open them concurrently or visitors may see error messages. Because of that you could lose site visitors as almost certainly many people won't revisit your internet site in the event that they have experienced issues or slow loading speeds. This is why you need to pay attention to the network components of any new hosting server which you acquire and not just to the main hardware like Processor, Random access memory or hard disk drive.
