rsync very slow, but not a network issue

I just performed the test again, this time timing the transfers with a 
stopwatch. (This time I was transferring a text file that consisted of 5 
million zeros, which is about 5MB.) Here's what I found.

    scp: 19 seconds
    rsync (no there): 17 seconds
    rsync (already there): 93 seconds

So it's taking much longer in real time when the file is already there, 
which is exactly the situation where rsync is supposed to accelerate teh 
transfer.

The cygwin machine is a Pentium III 1Ghz, and the eMac is a bit faster I 
believe. This should be fast enough that it's not bottlenecking on the 
hash computation, I think.

Cheers,
Alexis
