zfs discuss - Jun 2010 - Interesting ACM Queue article - zfs implications?

Hi all,

I am not a developer, but I have a background in engineering and a strong
interest in performance and optimization.  A recent Slashdot reference really
piqued my interest.  The reference is to an ACM Queue article that challenges
some conventional wisdom regarding algorithm performance when memory paging is
taken into consideration.  As file systems and ZFS in particular deal with block
hierarchies, I was curious if some of the principles discussed in the article
might have substantial performance implications for ZFS or de-dup (e.g. in
reducing the DDT memory thrashing and performance hit that can take place when
deleting large datasets from a de-duped pool).

The ACM Queue article URL is below:

Any thoughts?  Thanks in advance.
