Daniel Glenn has a public service announcement on Sharepoint maximum degree of parallelism:
For my first install test, I was using a service account that did have administrative rights on SQL as well. I looked at the setting in SQL and SharePoint 2016 did change the Maximum Degree Of Parallelism setting to 1. So, the story is, as of now anyway (we are dealing with Preview software), SharePoint Server 2016 requires MAXDOP=1.
Kidding about Sharepoint aside, if you do have Sharepoint in your environment, it’s worth knowing how to configure it correctly.
