why is "find" SUPER fast on ubuntu and not on cygwin
I have a directory tree on my ubuntu which consists of 15000 files and 8Gig of space.

At the command line, I put in:

time find "*.gz"

and it comes back with a response in less than 0.1 seconds.

I do the same thing on my cygwin system and it takes much longer.

My personal machine is much faster. Quad core machine, etc...

Unless I am fooling myself, I am seeing 2000 to 10000 times faster.

any thoughts would be appreciated.

dh_install

DH_INSTALL(1)							     Debhelper							     DH_INSTALL(1)

NAME

       dh_install - install files into package build directories

SYNOPSIS

       dh_install [-Xitem] [--autodest] [--sourcedir=dir] [debhelperoptions] [file|dir...destdir]

DESCRIPTION

       dh_install is a debhelper program that handles installing files into package build directories. There are many dh_install* commands that
       handle installing specific types of files such as documentation, examples, man pages, and so on, and they should be used when possible as
       they often have extra intelligence for those particular tasks. dh_install, then, is useful for installing everything else, for which no
       particular intelligence is needed. It is a replacement for the old dh_movefiles command.

       This program may be used in one of two ways. If you just have a file or two that the upstream Makefile does not install for you, you can
       run dh_install on them to move them into place. On the other hand, maybe you have a large package that builds multiple binary packages. You
       can use the upstream Makefile to install it all into debian/tmp, and then use dh_install to copy directories and files from there into the
       proper package build directories.

       From debhelper compatibility level 7 on, dh_install will fall back to looking in debian/tmp for files, if it does not find them in the
       current directory (or wherever you've told it to look using --sourcedir).

FILES

       debian/package.install
	   List the files to install into each package and the directory they should be installed to. The format is a set of lines, where each
	   line lists a file or files to install, and at the end of the line tells the directory it should be installed in. The name of the files
	   (or directories) to install should be given relative to the current directory, while the installation directory is given relative to
	   the package build directory. You may use wildcards in the names of the files to install.

	   Note that if you list exactly one filename or wildcard-pattern on a line by itself, with no explicit destination, then dh_install will
	   automatically guess the destination to use, the same as if the --autodest option were used.

       debian/not-installed
	   Used with the deprecated --list-missing and --fail-missing options.	Please refer to dh_missing(1) for the documentation of this file.

OPTIONS

       --list-missing
	   Deprecated: Please use dh_missing --list-missing instead.  If you use this option, dh_install will call dh_missing with that option
	   after it has processed all the files.  Please see dh_missing(1) for the documentation of this option.

	   This option is removed in compat 12.

       --fail-missing
	   Deprecated: Please use dh_missing --fail-missing instead.  If you use this option, dh_install will call dh_missing with that option
	   after it has processed all the files.  Please see dh_missing(1) for the documentation of this option.

	   This option is removed in compat 12.

       --sourcedir=dir
	   Look in the specified directory for files to be installed.

	   Note that this is not the same as the --sourcedirectory option used by the dh_auto_* commands. You rarely need to use this option,
	   since dh_install automatically looks for files in debian/tmp in debhelper compatibility level 7 and above.

       --autodest
	   Guess as the destination directory to install things to. If this is specified, you should not list destination directories in
	   debian/package.install files or on the command line. Instead, dh_install will guess as follows:

	   Strip off debian/tmp (or the sourcedir if one is given) from the front of the filename, if it is present, and install into the dirname
	   of the filename. So if the filename is debian/tmp/usr/bin, then that directory will be copied to debian/package/usr/. If the filename
	   is debian/tmp/etc/passwd, it will be copied to debian/package/etc/.

       file|dir ... destdir
	   Lists files (or directories) to install and where to install them to.  The files will be installed into the first package dh_install
	   acts on.

LIMITATIONS

       dh_install cannot rename files or directories, it can only install them with the names they already have into wherever you want in the
       package build tree.

       However, renaming can be achieved by using dh-exec with compatibility level 9 or later.	An example debian/package.install file using dh-
       exec could look like:

	#!/usr/bin/dh-exec
	debian/default.conf => /etc/my-package/start.conf

       Please remember the following three things:

       o   The package must be using compatibility level 9 or later (see debhelper(7))

       o   The package will need a build-dependency on dh-exec.

       o   The install file must be marked as executable.

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
