I don't know what Qt Creator is. Please provide tools to build your code from the command line.

I did some playing around with your binary, but it's pretty hard to benchmark because I don't know what your tool is doing with respect to .gitignore, hidden files and binary files. Your output format is also non-standard and doesn't revert to a line-by-line format when piped into another tool, so it's exceptionally difficult to determine whether the match counts are correct. Either way, I don't see any evidence that fsrc is faster. That you're using a fast SIMD algorithm is somewhat irrelevant; ripgrep uses SIMD too.

On my copy of the Linux checkout (note the `-u` flags passed to ripgrep):

I originally tried to run `fsrc` on a single file (in order to better control the benchmark), but I got an error:

    $ time /tmp/fsrc 'Sherlock Holmes' /data/benchsuite/subtitles/2018/OpenSubtitles2018.raw.sample.en
    Error  : option '--term' cannot be specified more than once
    Usage  : fsrc [options] term
    Options:
      -h [ --help ]         Help
      -d [ --dir ] arg      Search folder
      -i [ --ignore-case ]  Case insensitive search
      -r [ --regex ]        Regex search (slower)
      --no-git              Disable search with 'git ls-files'
      --no-colors           Disable colorized output
      -q [ --quiet ]        only print status
