If you host your websites on a dedicated hosting server, you would expect that they will perform super fast and that the access speed to them will depend solely on the Internet connection of the visitors. Nevertheless, this is not going to be the case in case the hosting machine has lousy network connectivity or uses a network card, which simply cannot cope with high volume of traffic. If this is the situation, it shall take quite a long time for your websites to load if lots of people open them at the same time or visitors could see error messages. Because of that you might lose customers as in all probability many people will never return to your internet site in case they have experienced issues or slow loading speeds. That is why you must pay attention to the network components of any new server you acquire and not only to the main hardware which includes Processor, Random access memory or hard drive.
