Overall it should be (and is) faster than 1.5, except for some
operations that might be slower in 2.0. For example there was a bug in
NOT IN (select...) or value <> ALL(select...) processing when you can
get bad results when index is used. It's fixed in 2.0, but without index
use, it could be way slower than before.
