Now that profiling works under Cygwin Emacs (thanks Ken and Eli!), I can
report the following when playing a couple of seconds with Dired-jump
(which I find much slower on Cygwin Emacs than on Windows Emacs).

In GNU Emacs 24.5.1 (x86_64-unknown-cygwin)
of 2015-06-23 on desktop-new
Windowing system distributor `Microsoft Corp.', version 6.3.9600
Configured using:
`configure --srcdir=/home/kbrown/src/cygemacs/emacs-24.5-2.x86_64/src/emacs-24.5 --prefix=/usr --exec-prefix=/usr --localstatedir=/var --sysconfdir=/etc --docdir=/usr/share/doc/emacs --htmldir=/usr/share/doc/emacs/html -C --with-w32

CPPFLAGS= LDFLAGS='
As I see there's an advice on `find-file', yes that's true; here's mine:
--8<---------------cut here---------------start------------->8---
(defadvice find-file (around my/find-file activate)
"Open the file named FILENAME and report time spent."
(let ((filename (ad-get-arg 0))
(find-file-time-start (float-time)))
(message "(Info) Finding file %s..." filename)
ad-do-it
(message "(Info) Found file %s in %.2f s" filename
(- (float-time) find-file-time-start))))
--8<---------------cut here---------------end--------------->8---
Other couple of (innocent) customs:
--8<---------------cut here---------------start------------->8---
(global-set-key (kbd "M-x") #'helm-M-x)
(require 'dired-x)
--8<---------------cut here---------------end--------------->8---

This seems to point to get-free-disk-space, which on Cygwin invokes
the 'df' program, whereas the native w32 build calls a function to get
the same info.
You also seem to have Helm active, so perhaps these two factors
together make 'df' invocation much slower than the w32 API call.
