What happens if you do a "dry run", i.e. with the -n option? That way you
can tell if it's network-related. I've found that network speed with
cygwin stuff is pretty sad. For example, using Tridge's socklib network
speed test (bewdiful - thanks Tridge!), I get 2MB/s under Win2k+cygwin,
vs. 10MB/s under Linux, same box in both cases.
You might also try the -malign-double (or whatever the heck it
is) compile option. I doubt this is relevant since you're using the -W
rsync option and hence not doing checksumming, but some of my unrelated
code is awful unless I specify the above.
Good luck.
