runBinary calls naiveIndexOf. You're not testing binaryIndexOf.
You are right.
This is fixed example:

and results at dpaste.dzfl.pl:
-----
SIMD: TickDuration(151000)
Binary: TickDuration(255000)
Naive: TickDuration(459000)
So SIMD version ~1.68 faster than binary
That's a healthy margin. It may get eroded by startup/finish codes that
need to get to the first aligned chunk and handle the misaligned data at
the end, etc. But it's a solid proof of concept. -- Andrei
