Re: Unexpected SQL performance behavior

The one thing to remember about performance testing SQL is that you are

Meaning that the behavior will change if the data set size or the system's
size and/or workload are different.

I think people would do well to apply that mindset to any kind of
performance testing, not just SQL.

But you're probably right that it is especially true for SQL, given
that the whole philosophy behind SQL is that we should tell it what we
want, and then let it figure out how to get it.
