Your VPN provider would be the bottleneck, not the VPN itself, in which case if you take a performance hit you should explore other VPN providers. But to tunnel all of your home traffic you can either (1) buy a router that supports VPN tunneling or (2) try and save some money by buying a generic router and flashing it with something like DD-WRT, which would give you an OpenVPN client which would allow you to do the same thing, just with cheaper hardware. Once set up, whenever your router boots it will connect the VPN and all of your traffic will go over that connection.
