I think that's something we can live with. Colorizing is already significant overhead, and if performance is important, don't do it:
/usr$ time ls --color=yes -R > /dev/null real 0m23.871s user 0m1.315s sys 0m22.513s
/usr$ time ls --color=no -R > /dev/null real 0m3.707s user 0m0.636s sys 0m3.060s
(Actually average of three runs, after discarding one.)
