@sam, can you test this one too, just curious, not sure if this helps performance wise..
It is a good suggestion to do a performance test. I like general tools like PatternSplitCM for the ease with which they allow you to solve a problem quickly. Most of the time a focused, working solution will outperform a general tool. But the general tool may be a good, bootstrap approach to get your code working.
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
