Just another report of performance improvements with recent releases...

I've been using the Hadoop project off and on for the last
year in some
ongoing work studying Wikipedia. One of the tasks I
developed computes the
revision-to-revision diff across all edits in the Wikipedia
history. From
the time I first developed the job (last summer) to the
latest operation
(last week, running on the 0.13.0 release), I've seen a
pretty remarkable
increase in performance. Even though the the input size has
more than
doubled, the time to run the job on Hadoop has dropped by
half, for a
roughly 4x overall improvement in performance.  Thanks
everyone!
