The 50% faster number above is not about better query plans. This is 50%
faster at the low-level grunt work of moving bits on and off disk and
search b-trees. We have achieved this by incorporating hundreds of
micro-optimizations. Each micro-optimization might improve the performance
by as little as 0.05%. If we get one that improves performance by 0.25%,
that is considered a huge win. Each of these optimizations is unmeasurable
