This has to be a network-level problem. IIRC, there are some threads in
our archives discussing possibly-related performance issues seen with
Windows' TCP stack. Don't recall details, but I think in some cases
the problem was traced to third-party add-ons to the Windows stack.
You might want to check just what you're running there.
