ls -lR too slow

I have a shared folder on my desktop which I have mapped as Z: drive on 
my laptop. Both machines are running Vista+SP1. My laptop has a recent 
version of Cygwin. When I do "ls -lR /cygdrive/z" it takes very long. 
There are only about 700 files on Z: totalling only 100 MB. When I 
monitor network counters on laptop, I see that a whopping 90 MB were 
downloaded for a payload (file list) of only 60 KB. Out of curiosity, I 
did the same experiment between two linux machines configured as NFS 
client+server. The ls -lR command on very similar directory tree whet 
very fast and only 0.5 MB were downloaded for the same payload. Cygwin 
was about 200 times slower. Is that normal?
