I should absolutely know not to report a number without a citation.
I was thinking of this report: http://www.linux.com/articles/41348
but it is actually comparing Linux vs other Unixlike OSs.
The Linux happens to be Gentoo, and the comments cite
Gentoo's "unfair advantage" because it is compiled with optimization!

So I shouldn't have claimed a performance advantage against other
distributions.  Might be true, but not supported by this study.
