mlocate by design doesn't thrash the cache as much.  People using
slocate (distros other than Redhat ;) are going to be hit worse.  See
http://carolina.mff.cuni.cz/~trmac/blog/mlocate/

updatedb by itself doesn't really bug me, its just that on occasion
its still running at 7am which then doesn't assist my single spindle
come swapin of the other apps!  I'm considering getting one of the old
ide drives out in the garage and shifting swap onto it.  The swap
prefetch patch has mainly assisted me in the "state A -> B -> A"
scenario.  A lot.
