Rob Bosch had similar performance problems on Windows and traced them
to highly fragmented files created by rsync.  I wrote a
quick-and-dirty patch to make rsync advise Windows of the eventual
file size in advance, allowing Windows to set aside a contiguous
region on disk; Rob found that it improved the performance
dramatically.  In case you want to try the patch, it is linked from
this message:
