They are difficult to explain, but the result is that the optimizer make quicker and better choices in how to execute queries, resulting in improved performance. The close relationship between our developers and users reporting problems allows us to make rapid and complex optimizer improvements that would be very difficult for lose-source companies to emulate.

I'd suggest removing the paragraph entirely, on the grounds that it is
content-free fluff.
