If you host your internet sites on a dedicated hosting server, you would expect that they'll perform extremely fast and that the access speed to them will depend exclusively on the Internet connection of the website visitors. Having said that, this won't be the case in case the server has lousy network connectivity or employs a network card, which just cannot handle high volume of site traffic. If this is the situation, it'll take a while for your websites to load if lots of people open them simultaneously or visitors could see error messages. Consequently you might lose website visitors as probably many people will never revisit your internet site in the event that they have experienced problems or slow loading speeds. This is why you ought to pay attention to the network components of any new hosting machine which you purchase and not just to the main hardware which includes Processor, RAM or hard drive.
