    @fommil Yes, I mentioned the benchmark suite from Peter to @srowen in my 
previous comment, but it is designed for dense linear algebra. I put some of 
the code I used to test sparse linear algebra operations to 
https://github.com/mengxr/linalg-test. It only contains a small subset of the 
operations needed to support sparse data in existing algorithms in MLlib. I 
will try to use the upcoming release of breeze and add more tests later.
