QuestionSQL 2000 to 2008R2 Query Performance Pinmembercjb1104-Oct-12 6:13 
We've upgraded one of our systems to SQL 2008R2 and certain parts are running like a dog. One statement that would have taken an average of 20-40mins on the old box, took from 11:40 to 00:35. Its not every statement but odd ones.
 
Its a 2 cpu box, and the cpu usage sits a 50%, there's hardly any activity in activity monitor (no significant resource waits etc, no io, or requests)
 
Unfortunatley this didn't happen during conversion, system test or uat, so we've imp'ed, and now hitting these issuesFrown | :(
 
Has anybody got some hints, places to look, good resources to read up on?
 
One thing we would like to work out, is it a fact, 2008 does things differently and query design, indexes etc need to be re-developed/analysed?
