Hello,
I am using SQL Server 2008 R2 SE with 24 processors as shown below:
This is a standalone non clustered server. The MAXDOP setting is 8 as shown below:
These settings have been the same for more than an year. But since last week I am noticing that query is taking longer time to execute and complaining on 94% wait time is on CXPACKET. Does this necessarily mean the MAXDOP setting has to be changed?
I added a few indexes for this query and CXPacket is gone but the indexes are causing failures somewhere else. As soon as the indexes were disabled these failures are gone.
Experts I need your valuable thoughts on this. Thanks a bunch.
