Others already mentioned location. I'll just note that 'find' and 'ls
-lR' should have comparable speeds. find's output should be nicer to
parse.

A single 'find' is normally enough to cache the relevant directories.
E.g.:

real    3m48.317s
user    0m1.568s
sys     0m7.948s
tzafrir@sweetmorn:~$ time find /usr >/dev/null

real    0m13.977s
user    0m0.772s
sys     0m1.532s
tzafrir@sweetmorn:~$ time find /usr >/dev/null

real    0m0.956s
user    0m0.332s
sys     0m0.616s
tzafrir@sweetmorn:~$ time find /usr >/dev/null

real    0m0.968s
user    0m0.372s
sys     0m0.576s

Actually the second 'find' took way longer than I expected.
