IMHO home users should not change Jumbo packet size, most if not all home routing equipment has 1514 set as the default and more importantly few if any ISP connections support anything over 1514 MTU. source Turning IPv6 might help if your ISP has less than ideal IPv6 routes over the internet, currently it should be safe to disable it if it helps. (for a couple more years anyway) - If your computer doesn't have a public IPv6 IP address - you would have to turn it off on the router if it has one, some of these new home routers will tunnel Ipv6 to ipv4. Turning off RDC won't help home users at all, this is a feature developed for DFSR, which is essential on Windows Servers. However you probably don't use it at home and it is only used by programs that specifically call for it.
