   5Set GIT_PERF_7821_GREP_OPTS in the environment to pass options to
   6git-grep. Make sure to include a leading space,
   7e.g. GIT_PERF_7821_GREP_OPTS=' -w'. See p7820-grep-engines.sh for more
   8options to try.

  10If GIT_PERF_7821_THREADS is set to a list of threads (e.g. '1 4 8'
  11etc.) we will test the patterns under those numbers of threads.
