Probably neither of that. Some in depth aspects of socket implementation on
Windows and Linux differ, and Wine has to implement certain additional
processing in getsockname() to make it behave exactly as on Windows for UDP
sockets bound to specific IP addresses (otherwise some apps will be broken).
That was not a problem for other applications as getsockname() is not something
the applications usually call in their time critical paths.

Can you please try the patch which I sent upstream [1] if it is still fixes the
car speed? I tested it myself with the load indicator and it looks the same as
with the initial version of the patch, but just in case.
