Grant Ingersoll commented on MAHOUT-588:
----------------------------------------

I'm guessing he means one run of the clustering algorithm, not one iteration of 
the k-means algorithm, but I'll let him say for sure

> Benchmark Mahout's clustering performance on EC2 and publish the results

> For Taming Text, I've commissioned some benchmarking work on Mahout's 
> clustering algorithms.  I've asked the two doing the project to do all the 
> work in the open here.  The goal is to use a publicly reusable dataset (for 
> now, the ASF mail archives, assuming it is big enough) and run on EC2 and 
> make all resources available so others can reproduce/improve.
> I'd like to add the setup code to utils (although it could possibly be done 
> as a Vectorizer) and the publication of the results will be put up on the 
> Wiki as well as in the book.  This issue is to track the patches, etc.
