I have been wondering about that myself, but I don't know the answer.
On the other hand, I just tried the following experiment:

$ time find linux > /dev/null

real	0m19.526s
user	0m0.073s
sys	0m0.273s

$ time find linux > /dev/null

real	0m0.149s
user	0m0.052s
sys	0m0.097s

So warming the cache makes a significant difference, but not in comparison with
your 8 minutes.
