Why do you think you have a performance issue?

What activity is it? with that I mean to ask if its a query or SP or job that is taking too long all of a sudden..

Also as Gail said why do think it is a performance issue all of a sudden...

Is there any blocking?

Has the volumes of data changed?

Are your indexes defragmented and your stats up to date?

There's a thousand things that can cause that to happen. Find out what changed and you will have your answer.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Sam - Now would be a time to work through the execution plan for that stored procedure to make sure that it has all the indexes that it needs. You might be able to pick up where one might be missing / dropped.

Additionally, without having any baseline data from which to work from it is hard to say whether your server is behaving "normally" or not as we don't know what "normal" is. Know what I mean.

So, start simple. Focus on the stored procedure getting it to perform the best you can. If you want you can save the execution plan out to a file from SSMS. Rename it with a .txt extension and attach it here so that we can look at it.

Thanks.

David
