So what's happening? If you sit down with a copy op "top" in one
terminal and updatedb in another, what does it show?

Just tested that, there's a steady increase in the useage of buff

Great. Now concentrate on the "swpd" column, as it's the only thing
relevant here. The fact that an updatedb run fills/replaces caches is
completely and utterly unsurprising and not something swap-prefetch helps
with. The only thing it does is bring back stuff from _swap_.

;)

I have 2Gb of RAM and I never ever touched swap on all my work loads. I was 
just showing the behavior of updatedb on my desktop. I have never even looked 
at the swap-prefetch patch (for obvious reasons). I think people should also 
look at their /proc/sys/vm/overcommit_ratio
