Hi Everyone,
i have two problems:
1)
i have set maxdop=8 to my sql instance , but when i am looking through sp_who2 some query sessions are generating up 17 parellel threads.what may be the causes of this issue.
2) LATCH_EX and CXPACKET waitstates are too high , does high LATCH_EX and CXPACKET waitstates can cause to CPU spikes and how to troubleshoot what is causing to high LATCH_EX and CXPACKET.
