How fast a website will open would depend not only on the Internet connection of the visitor, but also on the online connectivity of the hosting server where the internet site is hosted and on the network infrastructure - routers, server network card, and so forth. Slow connection or hardware that cannot handle a high volume of inbound and outgoing traffic might have powerful influence on the user experience of your site visitors and the overall performance of your site as people will probably see error messages that the website is not available or it shall take some time for your content to load. In the event that this kind of a thing occurs, it's unlikely that the website visitors shall return to the website. That is why you must always confirm the connectivity of any hosting server that you obtain and not just the main hardware components such as hard disk drive, cpu and physical memory.
