In case you host your websites on a dedicated server, you would expect that they will perform lightning fast and that the access speed to them shall depend solely on the Internet connection of the visitors. Having said that, this will not be the case in case the hosting server has lousy network connectivity or uses a network card, which simply just cannot handle high volume of traffic. If this is the case, it will take quite a long time for your internet sites to load if lots of people open them concurrently or visitors could see error messages. Consequently you might lose customers as probably many people will not revisit your website in the event that they have experienced problems or slow loading speeds. This is why you should pay attention to the network components of any new hosting server which you purchase and not just to the main hardware such as Processor, Random access memory or hard disk drive.
