and more directly, simply 

$ time kpsewhich -var-value TEXMFLOCAL
/usr/local/texlive/texmf-local

real	0m0.490s
user	0m0.476s
sys	0m0.011s

I realize that some other operations of kpsewhich 
have that overhead:
$ time kpsewhich hyperref.sty
/usr/local/texlive/2014/texmf-dist/tex/latex/hyperref/hyperref.sty

real	0m0.499s
user	0m0.484s
sys	0m0.011s

This is on mac os x mavericks, up-to-date TL2014
