there were only two other guys apart from me and Tassilo
(and David Kastrup) on this thread.
The OP was on Windows 8 and he has not commented since. I would
be very curious to know what was his issue, which may well be
completely unrelated to the Mac OS X/kpsewhich thing.
The other guy on Mac, I am not sure he really has AucTEX 11.88
He has not provided any usable information.
Again, during the fall of 2014, Adam Maxwell got even worse results
than my 2012 Mac Book Air with Mavericks. And he felt compelled
into profiling kpsewhich and obtained a 6 fold speed improvement.

I have vanilla TL2014 or TL2015 with no fiddling of texmf.cnf
files at all, aside from setting up the location of the local
tree and of the home tree and of the home var tree
TEXMFLOCAL = /usr/local/texlive/texmf-local-2014
TEXMFHOME = ~/Library/texmf
TEXMFVAR = ~/Library/texlive/2014/texmf-var
TEXMFCONFIG = ~/Library/texlive/2014/texmf-config
Nothing else changed.
Same for the pretest of TL2015.
Recall that Adam Maxwell divided by 6 the running time
of kpsewhich on Mac OS X, thus on TL2015 the situation
is less acute.
But still, 1/10th of a second for each call.
