And by the way, I don't think you can "configure a 2008 server to run as 2005" but a 2008 server can run databases at a lower compatibility level.
Try this query:
SELECT name, compatibility_level FROM sys.databases;
Compatibility level=100 indicates the database runs at 2008 compatibility. I believe 90 is the compatibility level for SQL 2005.
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.
