Actually, the accounting in Windows is not too swift. This looks like
local I/O problems, not network I/O problems. You can tell a bit more
if you run a windows specific tool to monitor performance.
(Both the network side and the local side)

BTW - Don't ask me about windows - I try to stay as far away from
it as possible. Unfortunately it is never far enough :-(
