On my screen the order of the lines in the query seem to get messed up,
I'm not sure if that's my email program or a copy/paste error.
From what I can see, you are using subselects in an IN statement,
which can be a problem if that has to be re-evaluated a lot.
It's hard for me to say more because I can't tell what the actual query
is at the moment.
