In the event that you host your websites on a dedicated hosting server, you would expect that they will perform extremely 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 server has lousy network connectivity or uses a network card, which simply just cannot handle high volume of traffic. If this is the situation, it'll take a long time for your internet sites to load if many people open them concurrently or visitors could see error messages. Thus you might lose site visitors as almost certainly many people will never revisit your 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 purchase and not just to the main hardware such as Processor, Ram memory or hard disk drive.
