I strongly advise you to not assume that just because an IPv4 address is 
"public" (which I'm reading as RFC1918) means that it's not NATed.

I learned the hard way that Tmobile, for one, squats on other 
organization's public IP space on their mobile network and NATs it to 
address space they are actually assigned.  What you really mean is if your 
IPv4 is not NATed, then it should not "feel slow", the type of address 
isn't necessarily an indicator.
