If the OP is looking for truer comparisons with Linux, I would say that using SAMBA on Linux is a better test than NFS. Of course, Cygwin is expected to be slower than Linux regardless. In terms of overall time/traffic with Cygwin, I'd recommend comparing the results of "DIR Z:" that Dave recommends above to "ls /cygdrive/z" (or "DIR /S Z:" to "ls -R /cygdrive/z"). If you need to use "-l" with "ls" and remote SAMBA shares, I'd recommend adding "smbntsec" to your "CYGWIN" environment variable. This should limit file accesses that "-l" (and other flags) can require. See the link below for more info: -- Larry Hall http://www.rfk.com RFK Partners, Inc.
