In case you host your websites on a dedicated hosting machine, you would expect that they will perform lightning fast and that the access speed to them will depend solely on the Internet connection of the site visitors. However, this is not going to be the case in the event that the server has lousy network connectivity or uses a network card, which just can't cope with high volume of traffic. If this is the situation, it shall take a long time for your websites to load if a lot of people open them at the same time or visitors might even see error messages. As a result you may lose visitors as most probably many people will never revisit your site in case they have experienced difficulties or slow loading speeds. That is why you should pay attention to the network components of any new hosting server that you get and not just to the main hardware which includes Processor, RAM or hard drive.
