Try a better benchmark, what you are probably measuring there is mostly
classloading, JIT, and similar startup costs. How long does it take on
the 1000th execution?
Also, unless you are specifically measuring query time when reexecuting
the same PreparedStatement many times, you should include the cost of
prepareStatement() in your measurements.
