It is indeed much faster.
More interestingly, compare4 is now 3 times faster than than compare1
and compare3. See results below.

Nice!
Now if your are REALLY trying to make things fast, for something so short
as 16 elements you could easily unroll the loops into a series of if
statements like in the other functions. This avoids the (very slight)
overhead of setting up the loop, and reading from / writing to the
iterator variables...
