Huh? From the NaCl paper: "The worst case performance overhead is

How do you get from 5% to 2x (100%)?

Have you actually run the same benchmarks on both and found them equal?
According to this comment no such benchmarks have been performed yet (at least by azakai): http://news.ycombinator.com/item?id=5228737
If not, declaring it "equal" seems a bit premature.
