Typically, transactions are done on a computer system that is located only within a company, using a database program rather than a web browser. Only after the transaction is completed within the company's database system is the information transmitted to the internet. Depending on the particular company, the transmission could take as long as several hours. (Or, in the case of RCI, days.

)
It's certainly possible that some other owner has a faster internet connection than you do. In fact, I'd say this is pretty much guaranteed, unless you are paying for a very fast connection. However, usually the big delay is in transferring the information from the company's database to the internet. Once the information is available to the internet, it is usually transmitted quite quickly. A faster internet connection might buy someone a few seconds, but that's probably it.
