Great. Now concentrate on the "swpd" column, as it's the only thing

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 see... thanks for the report :)
I think people should also look at their /proc/sys/vm/overcommit_ratio
In the sense that current stuff might be evicted earlier with no or little
overcommit?
