You keep saying "overhead" as if you know what you're talking about.
Either be more precise or stop making vague statements.

Msys does do posix translations.  It also does permutations on the
command line that cygwin does not.

I just ran a little test on msys and cygwin and found cygwin to
be consistently faster, in fact.  Here is what I tried:

time bin\sh -c "for f in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do for g in 1 2 3 4 5; do ls /bin/ls.exe >/dev/null ; done; done"

Of course, I cheated and used the cygwin that I've been working
on which has some potential performance benefits but this version
of cygwin was also compiled with --enable-debugging so it had some
possible performance hits as well.
