1/ how do you measure performances ? Anything which is not the median of
1-5K runs is meaningless.
You can see how he measures it in the code he posted.
2/ Don't use context, transform are usually better optimized by compilers
That really shouldn't

Ding! welcome to gcc-4.4 64bits compiler hellfest.
Try 4.5, 4.4 64bits can't inlien for w/e reason.

The compiler must really love the way proto evaluates an expression.
I still dont really know why. Usual speed-up in our use cases here is
