14 / 18 and I don't really program python (e.g. have no idea what the bcrypt lib's defaults in python are...) - but performance is something I've always cared about, and most of these are things you might happen to know. I'm surprised by the poor memory performance in his tests; my machine get's around an order of magnitude better performance in terms of throughput; which leads me to believe he's compiling using a very outdated gcc, and/or has really slow memory (laptops- you never know), and/or (reasonable, since he only mentioned -O2, but depends on the bitness of the compiler) he's compiling in "compatibility with 80386" mode. I think it's odd that people still haven't quite figured that one out yet. People use "-O2" all over the place, when that's rarely faster than "-O3", and they leave out one of the simplest optimization options the compiler has - "-march=native".
