Well, he just did point out such a case:

>>              no MB        with MB
>> LIKE      0.09 msec    0.08 msec
>> REGEX    0.09 msec    0.10 msec

But I agree with your conclusion.  If the worst penalty we can find is
that a regex comparison operator is 10% slower, we may as well turn it
on by default.  Most people will never notice the difference, and anyone
who really cares can always turn it off again.
