I tried it on Linux and FreeBSD. (I used the noatime option to mount.)
The Linux results showed no appreciable difference.
FreeBSD crashed when I ran the test on the Linux partition mounted with
noatime.
When I ran the test on the UFS partition, I saw the following:
mesquite:kev$ time find linux-2.4.2 -type f -print | xargs wc > /dev/null
real 0m30.553s
user 0m1.510s
sys 0m1.162s
mesquite:kev$ time find linux-2.4.2 -type f -print | xargs wc > /dev/null
real 0m4.904s
user 0m1.526s
sys 0m0.646s
These results are only slightly better than without noatime....
