Posix - Speed up "find" + "exec" command (recursive)

I learn some trick today on how to speed up find, exec command. Let check this out:

# let see how many files we have
$ find . -type f | wc -l
36367

# lets check every file status
$ time find . -type f -exec stat {} \; > /dev/null
real    0m40.107s
user    0m14.381s
sys     0m26.410s

# lets check every file status
$ time find . -type f -exec stat {} + > /dev/null
real    0m1.281s
user    0m0.626s
sys     0m0.656s

Wow that’s quite a huge difference! Impressive! All we did was swap the \; for a +.
