I'd forgotten to upgrade grep on my latest Macbook. In a large source code repo, looking for a fixed string with no wildcards: osx grep -r: real 2m37.786s user 2m27.034s sys 0m3.958s ggrep -r: real 0m12.842s user 0m5.754s sys 0m2.825s which is the difference between something I'd avoid and something I'll use.

Did you try setting the locale for OSX grep? LC_CTYPE=C https://news.ycombinator.com/item?id=4841168 https://news.ycombinator.com/item?id=4841168

Did you make sure to clear the filesystem cache between each run?

  The cache was warm for both measurements, which is more typical of my dev environment.
