I saw the thread below but it doesn't help me. I'm having a CPU issue with my SharePoint 2010 database in SQL 2008 R2. Several times per day it gets pegged between 95 and 100%. It doesn't matter what indexes I use because the queries that appear to be causing it are coded by Microsoft to use specific indexes (in particular AllUserData_PK) and I don't see any way to override it. I've tested the queries (they just grab list data) using my own indexes and they use 20,000 times less CPU than Microsoft's versions according to SQL Sentry. I've played around with the server-wide maxdop and it runs best set at 1. The server is a virtual machine with 2 quad-core CPUs.

It sounds like you'll need to contact Microsoft for this.

Do note that if you add indexes to a sharepoint DB, you lose all support from Microsoft it.

Thanks Gail And Tara. I removed the indexes once I was pretty sure what the problem was, not that they were used anyway.
