Perhaps; you'll have to read the source code to see if there are 
differences in geopy, or in the code that it relies on. But I suspect 
you *might* be seeing this bug:

It's a long thread, but the summary is: reading data over the Internet 
on Windows using some versions of Python is *sometimes* EXTREMELY slow 
compared to Linux or third party tools. This is due to a bug in the 
httplib module, which used a naive way of concatenating many little 
strings. Most of the time, Python has an optimization that can disguise 
how slow this is, but occasionally the optimization can fail.
