There isn't such a crippling difference between straight-line and code with
unconditional branches in it with modern processors. In fact, there's very
little measurable difference.

If you're looking for something to blame hurd performance on I'd suggest
the entire design of Mach, not inline asm vs procedure calls. Tossing a
few context switches into calls is a lot more expensive.

} You are very much forgetting _inline_ asm. And if you think that's
} unimportant for performance, well, as Al would say, go back playing
} with Hurd.
