that is largely dependent to what you are doing - there can still be
enormous differences, with or without SIMD.

now that quite some time has passed it's a lot of work.
And i don't see the actual merits since Miller has stated a few times
that he doesn't want to incorporate them.
It's no _real_ problem, because within 5-10 years autovectorization
functionalities in all major compilers will take that into account.
