I have a mapped network drive (F:) on Windows 7 that I can access very quickly from cmd.exe. For examle dir f: returns instantaneously.
But from cygwin, ls /f takes 20 seconds.
From cygwin:
$ uname
CYGWIN_NT-6.1
$ mount -p
Prefix Type Flags
/ user binmode
$ mount
C:/cygwin64/bin on /usr/bin type ntfs (binary,auto)
C:/cygwin64/lib on /usr/lib type ntfs (binary,auto)
C:/cygwin64 on / type ntfs (binary,auto)
C: on /c type ntfs (binary,posix=0,user,noumount,auto)
D: on /d type ntfs (binary,posix=0,user,noumount,auto)
F: on /f type ntfs (binary,posix=0,user,noumount,auto)
$ time ls /f
...
real 0m20.951s
user 0m0.000s
sys 0m0.030s
Any thoughts on the cause or how I can debug it?

It’s instant for me, but I use Windows 10. Is your Cygwin up to date? – Daniel B – 2017-05-31T16:05:59.090
@DanielB It's a very recent install of Cygwin (last couple of weeks). – pamphlet – 2017-05-31T16:08:44.810
