In the event that you host your internet sites on a dedicated hosting machine, you would expect that they will perform lightning fast and that the access speed to them will depend only on the Internet connection of the website visitors. Having said that, this won't be the case if the hosting server has lousy network connectivity or uses a network card, which simply cannot cope with high volume of site traffic. If this is the case, it'll take quite a long time for your internet sites to load if lots of people open them simultaneously or visitors may see error messages. Therefore you could lose website visitors as most likely many people will never revisit your site if they have experienced problems or slow loading speeds. This is why you should pay attention to the network components of any new server you acquire and not just to the main hardware which includes Central processing unit, RAM or hard disk drive.
