One quibble: the author at High Scalability refers to the authors of the paper collectively as "Google," but the lead authors, Lingjia Tang and Jason Mars, are professors at UC San Diego. Of course, they must have collaborated with Google and they may have done the work while doing summer internships in 2011 (CVs are at http://www.lingjia.org/ and http://jasonmars.org/).

Thanks for pointing out the error Scott. It should be fixed now.

A bit of a frustrating read. What exactly is a "performance swing"? Does that mean performance increased or decreased? I find the writing does not match the precision required to cover a highly technical topic.
