In case you host your websites on a dedicated hosting machine, you would expect that they shall perform extremely fast and that the access speed to them will depend exclusively on the Internet connection of the website visitors. However, this is not going to be the case in case the hosting machine has lousy network connectivity or relies on a network card, which simply just can't cope with high volume of site traffic. If this is the situation, it shall take quite a long time for your internet sites to load if a lot of people open them simultaneously or visitors might even see error messages. Because of that you may lose site visitors as almost certainly many people won't revisit your internet site if they have experienced difficulties or slow loading speeds. That's why you need to pay attention to the network components of any new server which you purchase and not only to the main hardware which includes Central processing unit, Ram memory or hard drive.
