Carlo,
It would have been more helpful if you had provided your cygwin version,
but even without it I could venture a guess...  The latest versions of
cygwin have ntsec on by default, and doing 'ls -l' will result in the user
lookup in the /etc/passwd (and /etc/group) file.  An easy way to test that
is to time 'ls -ln' and see if it's faster.  Another test would be to
*temporarily* turn off ntsec (by adding "nontsec" to your CYGWIN
environment variable and reloading cygwin1.dll by exiting all running
cygwin processes).  I say temporarily because ntsec is actually a very
useful feature to have on, and this is suggested only as a means to find
out whether it's the culprit.  You can restore the state by either
changing "nontsec" to "ntsec", or leaving it off altogether, as it's the
default now, and reloading cygwin1.dll again.
