Should not need anything special:

$ ls -dl / && getfacl / && icacls `cygpath -m /`	# sanitized:
drwxr-xr-x 1 $USER None 0 Mar 16 18:57 /

# file: /
# owner: $USER
# group: None
user::rwx
group::r-x
other::r-x
default:user::rwx
default:group::r-x
default:other::r-x

Those kinds of delays are often AD lookup for domain users and groups:
see /etc/nsswitch.conf for settings, and consider running cygserver at system or 
Cygwin startup to preload and cache the info.
