Concurrent filesystem scanning

I want to obtain file information (file name & size in bytes) for the files in a directory. But there are a lot of sub-directory (~ 1000) and files (~40 000).

Actually my solution is to use filepath.Walk() to obtain file information for each file. But this is quite long.

func visit(path string, f os.FileInfo, err error) error {
    if f.Mode().IsRegular() {
        fmt.Printf("Visited: %s File name: %s Size: %d bytes\n", path, f.Name(), f.Size())
    }
    return nil
}
func main() {
    flag.Parse()
    root := "C:/Users/HERNOUX-06523/go/src/boilerpipe" //flag.Arg(0)
    filepath.Walk(root, visit)
}

Is it possible to do parallel/concurrent processing using filepath.Walk()?
