You're hitting up against, what I feel is one of the most common
and most difficult to solve problems out there.
The best solution is to fix the SQL statements. Unfortunately,
it's quite possible that you won't be able to fix the application
that's causing the problem, becuase it's closed-source and
written by someone else. At that point, you're up against the
frustrating chore of convincing the application designer to
fix their lousy code, which is often impossible.
In the end, it seems that most people end up buying faster,
more expensive hardware to make up for lousy application design.
It's a damn shame, but that's what seems to happen a lot.
