Agreed. But when Tom pointed out the problem in your query you were
quite sure you couldn't be wrong. When I asked you to run explain to
see what kind of row estimate you got, I got no answer. This was a
query problem not a hardware tuning problem.

The best step for getting a good answer is forming a good question.

So, has changing the query made it faster? Did explain show what I
expect, a huge cartesian product? Just guessing.
